We're dividing 3539567 by 231 
Let's see how many times 231 fits into 3539567.

Moving on to step 1:
231 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 231

On to step 2:
35 divided by 231 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 231

Going ahead to step 3:
353 divided by 231 is 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 231 from 353, we get 122.
Grab the next digit (9) from the dividend, add it to 122, then carry on: 1229 / 231

Advancing to step 4:
The number 231 fits into 1229 5 times, leaving a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 1155 from 1229 and we're left with 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 231

Step 5:
745 divided by 231 is 3 with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 153.0
The remainder is 52 after subtracting 693 from 745.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 231

On to step 6:
When dividing 526 by 231, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 1532.0
If we subtract 462 from 526, we get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 231

On to step 7:
When dividing 647 by 231, we get 2 with a remainder of 185.
Use 2 as the next digit of our solution. 
Result so far: 15322.0
Subtracting 462 from 647 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 8:
231 goes into 1850 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 15322.8
Deduct 1848 from 1850 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
231 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 15322.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
231 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 15322.8
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 15322.8 with a remainder of 0.02.
