We're dividing 51661865 by 959 
We want to divide 51661865 by 959.

Advancing to step 1:
If we divide 5 by 959, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 959

Moving on to step 2:
959 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 959

Let's proceed to step 3:
959 can be fit into 516 0 times, resulting in a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 516, we end up with 516.
Grab the next digit (6) from the dividend, add it to 516, then carry on: 5166 / 959

On to step 4:
If we divide 5166 by 959, we get 5 and a remainder of 371.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 371 after subtracting 4795 from 5166.
Include the next digit (1) from the dividend after 371, then repeat: 3711 / 959

Going ahead to step 5:
959 goes into 3711 3 times with a remainder of 834.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 2877 from 3711 leaves us with 834.
Take the next digit (8) from the dividend and append it to 834, then repeat: 8348 / 959

On to step 6:
959 can be fit into 8348 8 times, resulting in a remainder of 676.
Record the quotient 8 as the next digit in the result. 
Result so far: 538.0
If we subtract 7672 from 8348, we get 676.
Append the next digit (6) from the dividend to 676 and continue with: 6766 / 959

Step 7:
When dividing 6766 by 959, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 5387.0
Deduct 6713 from 6766 and we're left with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 959

Going ahead to step 8:
When dividing 535 by 959, we get 0 with a remainder of 535.
Use 0 as the next digit of our solution. 
Result so far: 53870.0
Deduct 0 from 535 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Let's proceed to step 9:
959 can be fit into 5350 5 times, resulting in a remainder of 555.
Record the quotient 5 as the next digit in the result. 
Result so far: 53870.5
Subtracting 4795 from 5350 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 10:
If we divide 5550 by 959, we get 5 and a remainder of 755.
Use 5 as the next digit of our solution. 
Result so far: 53870.55
If we subtract 4795 from 5550, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

After the division, we end up with 53870.55 and a remainder of 0.755.
