Let's divide 81401983 by 523
We're looking to find how many times 523 goes into 81401983.

Moving on to step 1:
When dividing 8 by 523, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 523

Moving on to step 2:
523 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 523

Moving on to step 3:
The number 523 fits into 814 1 times, leaving a remainder of 291.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 523 from 814 and we're left with 291.
Include the next digit (0) from the dividend after 291, then repeat: 2910 / 523

Let's proceed to step 4:
523 goes into 2910 5 times with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 2615 from 2910 to get 295.
Fetch the next digit (1) from the dividend, attach it to 295 and continue: 2951 / 523

Step 5:
523 can be fit into 2951 5 times, resulting in a remainder of 336.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 2615 from 2951 leaves us with 336.
Append the next digit (9) from the dividend to 336 and continue with: 3369 / 523

Moving on to step 6:
523 goes into 3369 6 times with a remainder of 231.
The next digit of our result is 6. 
Result so far: 1556.0
If we subtract 3138 from 3369, we get 231.
Include the next digit (8) from the dividend after 231, then repeat: 2318 / 523

Moving on to step 7:
If we divide 2318 by 523, we get 4 and a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 15564.0
The remainder is 226 after subtracting 2092 from 2318.
Bring next digit (3) of the dividend behind the 226 and repeat the process: 2263 / 523

Step 8:
523 goes into 2263 4 times with a remainder of 171.
Put 4 as the next digit of the answer. 
Result so far: 155644.0
Subtract 2092 from 2263 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 9:
523 goes into 1710 3 times with a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 155644.3
The remainder is 141 after subtracting 1569 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 10:
When dividing 1410 by 523, we get 2 with a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 155644.32
If we subtract 1046 from 1410, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 11:
The number 523 fits into 3640 6 times, leaving a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 155644.326
The remainder is 502 after subtracting 3138 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 12:
523 goes into 5020 9 times with a remainder of 313.
Write down 9 as next digit of the result. 
Result so far: 155644.3269
The remainder is 313 after subtracting 4707 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 13:
3130 divided by 523 is 5 with a remainder of 515.
Record the quotient 5 as the next digit in the result. 
Result so far: 155644.32695
Deduct 2615 from 3130 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

On to step 14:
When dividing 5150 by 523, we get 9 with a remainder of 443.
Record the quotient 9 as the next digit in the result. 
Result so far: 155644.326959
Subtract 4707 from 5150 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 15:
The number 523 fits into 4430 8 times, leaving a remainder of 246.
Write down 8 as next digit of the result. 
Result so far: 155644.3269598
If we subtract 4184 from 4430, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 16:
2460 divided by 523 is 4 with a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 155644.32695984
The remainder is 368 after subtracting 2092 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 155644.32695984 with a remaining 3.68e-07.
