Let's divide 139531 by 74
We want to divide 139531 by 74.

Moving on to step 1:
74 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 74

Moving on to step 2:
The number 74 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 74

Going ahead to step 3:
139 divided by 74 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 65 after subtracting 74 from 139.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 74

Moving on to step 4:
The number 74 fits into 655 8 times, leaving a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 63 after subtracting 592 from 655.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 74

Advancing to step 5:
74 goes into 633 8 times with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 188.0
If we take 592 away from 633, we end up with 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 74

Let's proceed to step 6:
The number 74 fits into 411 5 times, leaving a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 1885.0
The remainder is 41 after subtracting 370 from 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
The number 74 fits into 410 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 1885.5
The remainder is 40 after subtracting 370 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
400 divided by 74 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1885.55
Deduct 370 from 400 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 1885.55 and a remainder of 0.03.
