We look at the division of 51408615 by 634 
Our goal is to divide 51408615 by 634.

Let's proceed to step 1:
634 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 634

Advancing to step 2:
The number 634 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 634

Moving on to step 3:
If we divide 514 by 634, we get 0 and a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 514, we get 514.
Take the next digit (0) from the dividend and append it to 514, then repeat: 5140 / 634

Going ahead to step 4:
If we divide 5140 by 634, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5072 from 5140 and we're left with 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 634

On to step 5:
634 goes into 688 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 634 from 688, we get 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 634

Going ahead to step 6:
The number 634 fits into 546 0 times, leaving a remainder of 546.
Put 0 as the next digit of the answer. 
Result so far: 810.0
The remainder is 546 after subtracting 0 from 546.
Fetch the next digit (1) from the dividend, attach it to 546 and continue: 5461 / 634

Step 7:
634 can be fit into 5461 8 times, resulting in a remainder of 389.
The number 8 becomes the next digit in our result. 
Result so far: 8108.0
The remainder is 389 after subtracting 5072 from 5461.
Include the next digit (5) from the dividend after 389, then repeat: 3895 / 634

On to step 8:
If we divide 3895 by 634, we get 6 and a remainder of 91.
Use 6 as the next digit of our solution. 
Result so far: 81086.0
The remainder is 91 after subtracting 3804 from 3895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
The number 634 fits into 910 1 times, leaving a remainder of 276.
The number 1 becomes the next digit in our result. 
Result so far: 81086.1
If we subtract 634 from 910, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 10:
If we divide 2760 by 634, we get 4 and a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 81086.14
The remainder is 224 after subtracting 2536 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 11:
2240 divided by 634 is 3 with a remainder of 338.
Write down 3 as next digit of the result. 
Result so far: 81086.143
Subtract 1902 from 2240 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 12:
If we divide 3380 by 634, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 81086.1435
If we take 3170 away from 3380, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
634 can be fit into 2100 3 times, resulting in a remainder of 198.
Put 3 as the next digit of the answer. 
Result so far: 81086.14353
Subtracting 1902 from 2100 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 14:
When dividing 1980 by 634, we get 3 with a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 81086.143533
Subtract 1902 from 1980 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 81086.143533 with a remaining 7.8e-06.
