Let's divide 81002657 by 839
We want to divide 81002657 by 839.

Moving on to step 1:
839 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 839

On to step 2:
The number 839 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 839

On to step 3:
839 goes into 810 0 times with a remainder of 810.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 810, we get 810.
Grab the next digit (0) from the dividend, add it to 810, then carry on: 8100 / 839

Going ahead to step 4:
8100 divided by 839 is 9 with a remainder of 549.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 549 after subtracting 7551 from 8100.
Grab the next digit (2) from the dividend, add it to 549, then carry on: 5492 / 839

Let's proceed to step 5:
The number 839 fits into 5492 6 times, leaving a remainder of 458.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 5034 from 5492 to get 458.
Append the next digit (6) from the dividend to 458 and continue with: 4586 / 839

Let's proceed to step 6:
4586 divided by 839 is 5 with a remainder of 391.
The number 5 becomes the next digit in our result. 
Result so far: 965.0
If we subtract 4195 from 4586, we get 391.
Take the next digit (5) from the dividend and append it to 391, then repeat: 3915 / 839

Going ahead to step 7:
When dividing 3915 by 839, we get 4 with a remainder of 559.
The next digit of our result is 4. 
Result so far: 9654.0
The remainder is 559 after subtracting 3356 from 3915.
Take the next digit (7) from the dividend and append it to 559, then repeat: 5597 / 839

Step 8:
If we divide 5597 by 839, we get 6 and a remainder of 563.
Use 6 as the next digit of our solution. 
Result so far: 96546.0
Deduct 5034 from 5597 and we're left with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 9:
839 goes into 5630 6 times with a remainder of 596.
The next digit of our result is 6. 
Result so far: 96546.6
If we subtract 5034 from 5630, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 10:
When dividing 5960 by 839, we get 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 96546.67
If we subtract 5873 from 5960, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
If we divide 870 by 839, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 96546.671
Subtract 839 from 870 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
The number 839 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 96546.671
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
839 goes into 3100 3 times with a remainder of 583.
The number 3 becomes the next digit in our result. 
Result so far: 96546.67103
The remainder is 583 after subtracting 2517 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Let's proceed to step 14:
839 goes into 5830 6 times with a remainder of 796.
Record the quotient 6 as the next digit in the result. 
Result so far: 96546.671036
The remainder is 796 after subtracting 5034 from 5830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 15:
If we divide 7960 by 839, we get 9 and a remainder of 409.
Record the quotient 9 as the next digit in the result. 
Result so far: 96546.6710369
Deduct 7551 from 7960 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 16:
839 can be fit into 4090 4 times, resulting in a remainder of 734.
Write down 4 as next digit of the result. 
Result so far: 96546.67103694
Deduct 3356 from 4090 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

The final result is 96546.67103694 with a remainder of 7.34e-07.
