We're dividing 86542851 by 662 
We want to figure out the number of times 86542851 can be divided by 662.

Going ahead to step 1:
8 divided by 662 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 662

Moving on to step 2:
662 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 662

On to step 3:
If we divide 865 by 662, we get 1 and a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 203 after subtracting 662 from 865.
Take the next digit (4) from the dividend and append it to 203, then repeat: 2034 / 662

Let's proceed to step 4:
662 goes into 2034 3 times with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 48 after subtracting 1986 from 2034.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 662

Advancing to step 5:
The number 662 fits into 482 0 times, leaving a remainder of 482.
Put 0 as the next digit of the answer. 
Result so far: 130.0
The remainder is 482 after subtracting 0 from 482.
Fetch the next digit (8) from the dividend, attach it to 482 and continue: 4828 / 662

On to step 6:
662 can be fit into 4828 7 times, resulting in a remainder of 194.
The next digit of our result is 7. 
Result so far: 1307.0
Subtracting 4634 from 4828 leaves us with 194.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 662

Let's proceed to step 7:
If we divide 1945 by 662, we get 2 and a remainder of 621.
Use 2 as the next digit of our solution. 
Result so far: 13072.0
If we subtract 1324 from 1945, we get 621.
Take the next digit (1) from the dividend and append it to 621, then repeat: 6211 / 662

Going ahead to step 8:
662 goes into 6211 9 times with a remainder of 253.
Record the quotient 9 as the next digit in the result. 
Result so far: 130729.0
If we take 5958 away from 6211, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 9:
When dividing 2530 by 662, we get 3 with a remainder of 544.
Write down 3 as next digit of the result. 
Result so far: 130729.3
Deduct 1986 from 2530 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 10:
The number 662 fits into 5440 8 times, leaving a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 130729.38
If we subtract 5296 from 5440, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
When dividing 1440 by 662, we get 2 with a remainder of 116.
The number 2 becomes the next digit in our result. 
Result so far: 130729.382
The remainder is 116 after subtracting 1324 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 12:
When dividing 1160 by 662, we get 1 with a remainder of 498.
Use 1 as the next digit of our solution. 
Result so far: 130729.3821
The remainder is 498 after subtracting 662 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 13:
When dividing 4980 by 662, we get 7 with a remainder of 346.
Put 7 as the next digit of the answer. 
Result so far: 130729.38217
Subtracting 4634 from 4980 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 14:
3460 divided by 662 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 130729.382175
The remainder is 150 after subtracting 3310 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
1500 divided by 662 is 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 130729.3821752
If we subtract 1324 from 1500, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 16:
The number 662 fits into 1760 2 times, leaving a remainder of 436.
Write down 2 as next digit of the result. 
Result so far: 130729.38217522
The remainder is 436 after subtracting 1324 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final result is 130729.38217522 with a remainder of 4.36e-07.
