We look at the division of 81203851 by 655 
Our goal is to divide 81203851 by 655.

Step 1:
The number 655 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 655

Going ahead to step 2:
The number 655 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 655

Advancing to step 3:
When dividing 812 by 655, we get 1 with a remainder of 157.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 655 from 812 and we're left with 157.
Fetch the next digit (0) from the dividend, attach it to 157 and continue: 1570 / 655

Going ahead to step 4:
1570 divided by 655 is 2 with a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1310 from 1570, we get 260.
Grab the next digit (3) from the dividend, add it to 260, then carry on: 2603 / 655

Advancing to step 5:
655 goes into 2603 3 times with a remainder of 638.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtracting 1965 from 2603 leaves us with 638.
Take the next digit (8) from the dividend and append it to 638, then repeat: 6388 / 655

Let's proceed to step 6:
If we divide 6388 by 655, we get 9 and a remainder of 493.
The next digit of our result is 9. 
Result so far: 1239.0
Subtracting 5895 from 6388 leaves us with 493.
Grab the next digit (5) from the dividend, add it to 493, then carry on: 4935 / 655

Moving on to step 7:
4935 divided by 655 is 7 with a remainder of 350.
Record the quotient 7 as the next digit in the result. 
Result so far: 12397.0
Deduct 4585 from 4935 and we're left with 350.
Bring next digit (1) of the dividend behind the 350 and repeat the process: 3501 / 655

Let's proceed to step 8:
655 can be fit into 3501 5 times, resulting in a remainder of 226.
Put 5 as the next digit of the answer. 
Result so far: 123975.0
If we subtract 3275 from 3501, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 9:
655 can be fit into 2260 3 times, resulting in a remainder of 295.
Use 3 as the next digit of our solution. 
Result so far: 123975.3
Subtracting 1965 from 2260 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 10:
When dividing 2950 by 655, we get 4 with a remainder of 330.
The next digit of our result is 4. 
Result so far: 123975.34
Deduct 2620 from 2950 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 11:
When dividing 3300 by 655, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 123975.345
If we take 3275 away from 3300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
250 divided by 655 is 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 123975.345
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 13:
If we divide 2500 by 655, we get 3 and a remainder of 535.
Use 3 as the next digit of our solution. 
Result so far: 123975.34503
Deduct 1965 from 2500 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 14:
655 can be fit into 5350 8 times, resulting in a remainder of 110.
The next digit of our result is 8. 
Result so far: 123975.345038
Subtracting 5240 from 5350 leaves us 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.

Going ahead to step 15:
655 can be fit into 1100 1 times, resulting in a remainder of 445.
Use 1 as the next digit of our solution. 
Result so far: 123975.3450381
Subtract 655 from 1100 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 16:
655 goes into 4450 6 times with a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 123975.34503816
Subtracting 3930 from 4450 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final outcome is 123975.34503816, with a leftover of 5.2e-07.
