83102574 ÷ 531 
We're looking to find how many times 531 goes into 83102574.

Moving on to step 1:
531 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 531

Going ahead to step 2:
When dividing 83 by 531, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 531

Moving on to step 3:
531 can be fit into 831 1 times, resulting in a remainder of 300.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 531 from 831, we get 300.
Take the next digit (0) from the dividend and append it to 300, then repeat: 3000 / 531

Step 4:
If we divide 3000 by 531, we get 5 and a remainder of 345.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 345 after subtracting 2655 from 3000.
Grab the next digit (2) from the dividend, add it to 345, then carry on: 3452 / 531

On to step 5:
When dividing 3452 by 531, we get 6 with a remainder of 266.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Subtract 3186 from 3452 to get 266.
Take the next digit (5) from the dividend and append it to 266, then repeat: 2665 / 531

Step 6:
The number 531 fits into 2665 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 1565.0
Subtracting 2655 from 2665 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 531

On to step 7:
107 divided by 531 is 0 with a remainder of 107.
Put 0 as the next digit of the answer. 
Result so far: 15650.0
If we subtract 0 from 107, we get 107.
Bring next digit (4) of the dividend behind the 107 and repeat the process: 1074 / 531

Going ahead to step 8:
If we divide 1074 by 531, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 156502.0
If we subtract 1062 from 1074, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 531, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 156502.0
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
531 goes into 1200 2 times with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 156502.02
Subtract 1062 from 1200 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
When dividing 1380 by 531, we get 2 with a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 156502.022
If we take 1062 away from 1380, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Our division results in 156502.022 with a remaining 0.0318.
