We're dividing 85966142 by 455 
We want to figure out the number of times 85966142 can be divided by 455.

Going ahead to step 1:
The number 455 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 455

Let's proceed to step 2:
455 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 455

Advancing to step 3:
If we divide 859 by 455, we get 1 and a remainder of 404.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 455 from 859 and we're left with 404.
Bring next digit (6) of the dividend behind the 404 and repeat the process: 4046 / 455

Let's proceed to step 4:
455 can be fit into 4046 8 times, resulting in a remainder of 406.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 3640 away from 4046, we end up with 406.
Take the next digit (6) from the dividend and append it to 406, then repeat: 4066 / 455

On to step 5:
4066 divided by 455 is 8 with a remainder of 426.
Write down 8 as next digit of the result. 
Result so far: 188.0
Subtracting 3640 from 4066 leaves us with 426.
Take the next digit (1) from the dividend and append it to 426, then repeat: 4261 / 455

Step 6:
The number 455 fits into 4261 9 times, leaving a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 1889.0
Subtracting 4095 from 4261 leaves us with 166.
Append the next digit (4) from the dividend to 166 and continue with: 1664 / 455

Let's proceed to step 7:
The number 455 fits into 1664 3 times, leaving a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 18893.0
If we subtract 1365 from 1664, we get 299.
Fetch the next digit (2) from the dividend, attach it to 299 and continue: 2992 / 455

Let's proceed to step 8:
455 goes into 2992 6 times with a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 188936.0
If we subtract 2730 from 2992, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 9:
If we divide 2620 by 455, we get 5 and a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 188936.5
The remainder is 345 after subtracting 2275 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 10:
If we divide 3450 by 455, we get 7 and a remainder of 265.
The next digit of our result is 7. 
Result so far: 188936.57
Deduct 3185 from 3450 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 11:
455 can be fit into 2650 5 times, resulting in a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 188936.575
Subtracting 2275 from 2650 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 12:
3750 divided by 455 is 8 with a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 188936.5758
Deduct 3640 from 3750 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
455 can be fit into 1100 2 times, resulting in a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 188936.57582
If we subtract 910 from 1100, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
When dividing 1900 by 455, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 188936.575824
Subtract 1820 from 1900 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
The number 455 fits into 800 1 times, leaving a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 188936.5758241
Subtract 455 from 800 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 16:
If we divide 3450 by 455, we get 7 and a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 188936.57582417
Deduct 3185 from 3450 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final outcome is 188936.57582417, with a leftover of 2.65e-07.
