We look at the division of 442953 by 86 
We want to figure out the number of times 442953 can be divided by 86.

Going ahead to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 86

Going ahead to step 2:
When dividing 44 by 86, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 86

Advancing to step 3:
442 divided by 86 is 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 430 from 442 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 86

On to step 4:
If we divide 129 by 86, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 86 from 129 and we're left with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 86

Going ahead to step 5:
If we divide 435 by 86, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
Deduct 430 from 435 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 86

Moving on to step 6:
53 divided by 86 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 5150.0
Subtract 0 from 53 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 86 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 5150.6
The remainder is 14 after subtracting 516 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
86 goes into 140 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 5150.61
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
If we divide 540 by 86, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5150.616
Subtracting 516 from 540 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
240 divided by 86 is 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 5150.6162
If we subtract 172 from 240, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
86 can be fit into 680 7 times, resulting in a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 5150.61627
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
86 goes into 780 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 5150.616279
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 86 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 5150.616279
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
If we divide 600 by 86, we get 6 and a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 5150.61627906
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 5150.61627906, with a leftover of 8.4e-08.
