We look at the division of 961588 by 51 
Our goal is to divide 961588 by 51.

Advancing to step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 51

On to step 2:
If we divide 96 by 51, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 51 from 96 to get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 51

Moving on to step 3:
51 can be fit into 451 8 times, resulting in a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 43 after subtracting 408 from 451.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 51

Let's proceed to step 4:
435 divided by 51 is 8 with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 188.0
Deduct 408 from 435 and we're left with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 51

Going ahead to step 5:
The number 51 fits into 278 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 1885.0
The remainder is 23 after subtracting 255 from 278.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 51

Going ahead to step 6:
51 goes into 238 4 times with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 18854.0
If we take 204 away from 238, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
The number 51 fits into 340 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 18854.6
Subtracting 306 from 340 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
The number 51 fits into 340 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 18854.66
Deduct 306 from 340 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 18854.66 and a remainder of 0.034.
