51716314 ÷ 415 
We want to divide 51716314 by 415.

Advancing to step 1:
415 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 415

On to step 2:
415 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 take 0 away from 51, we end up with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 415

Advancing to step 3:
517 divided by 415 is 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 415 away from 517, we end up with 102.
Bring next digit (1) of the dividend behind the 102 and repeat the process: 1021 / 415

Step 4:
When dividing 1021 by 415, we get 2 with a remainder of 191.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 830 away from 1021, we end up with 191.
Append the next digit (6) from the dividend to 191 and continue with: 1916 / 415

Advancing to step 5:
415 goes into 1916 4 times with a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtracting 1660 from 1916 leaves us with 256.
Bring next digit (3) of the dividend behind the 256 and repeat the process: 2563 / 415

Step 6:
415 goes into 2563 6 times with a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 1246.0
Subtracting 2490 from 2563 leaves us with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 415

Step 7:
415 goes into 731 1 times with a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 12461.0
Subtracting 415 from 731 leaves us with 316.
Take the next digit (4) from the dividend and append it to 316, then repeat: 3164 / 415

On to step 8:
415 can be fit into 3164 7 times, resulting in a remainder of 259.
Write down 7 as next digit of the result. 
Result so far: 124617.0
Subtract 2905 from 3164 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 9:
The number 415 fits into 2590 6 times, leaving a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 124617.6
Subtracting 2490 from 2590 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
1000 divided by 415 is 2 with a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 124617.62
Subtract 830 from 1000 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
If we divide 1700 by 415, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 124617.624
If we take 1660 away from 1700, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 415, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 124617.624
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
The number 415 fits into 4000 9 times, leaving a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 124617.62409
If we take 3735 away from 4000, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 14:
415 can be fit into 2650 6 times, resulting in a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 124617.624096
Deduct 2490 from 2650 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
If we divide 1600 by 415, we get 3 and a remainder of 355.
The number 3 becomes the next digit in our result. 
Result so far: 124617.6240963
If we subtract 1245 from 1600, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 16:
415 can be fit into 3550 8 times, resulting in a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 124617.62409638
Subtracting 3320 from 3550 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final result is 124617.62409638 with a remainder of 2.3e-07.
