51612340 ÷ 415 
We want to divide 51612340 by 415.

Moving on to step 1:
5 divided by 415 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 415

Going ahead to step 2:
415 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 415

Let's proceed to step 3:
If we divide 516 by 415, we get 1 and a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 415 from 516 and we're left with 101.
Fetch the next digit (1) from the dividend, attach it to 101 and continue: 1011 / 415

On to step 4:
415 can be fit into 1011 2 times, resulting in a remainder of 181.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 830 away from 1011, we end up with 181.
Append the next digit (2) from the dividend to 181 and continue with: 1812 / 415

On to step 5:
1812 divided by 415 is 4 with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 124.0
The remainder is 152 after subtracting 1660 from 1812.
Fetch the next digit (3) from the dividend, attach it to 152 and continue: 1523 / 415

Going ahead to step 6:
The number 415 fits into 1523 3 times, leaving a remainder of 278.
The next digit of our result is 3. 
Result so far: 1243.0
If we subtract 1245 from 1523, we get 278.
Fetch the next digit (4) from the dividend, attach it to 278 and continue: 2784 / 415

On to step 7:
415 goes into 2784 6 times with a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 12436.0
The remainder is 294 after subtracting 2490 from 2784.
Take the next digit (0) from the dividend and append it to 294, then repeat: 2940 / 415

Let's proceed to step 8:
If we divide 2940 by 415, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 124367.0
If we subtract 2905 from 2940, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
415 goes into 350 0 times with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 124367.0
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
If we divide 3500 by 415, we get 8 and a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 124367.08
Subtract 3320 from 3500 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
If we divide 1800 by 415, we get 4 and a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 124367.084
Subtracting 1660 from 1800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
1400 divided by 415 is 3 with a remainder of 155.
Write down 3 as next digit of the result. 
Result so far: 124367.0843
Subtracting 1245 from 1400 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 13:
415 can be fit into 1550 3 times, resulting in a remainder of 305.
The next digit of our result is 3. 
Result so far: 124367.08433
Subtract 1245 from 1550 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The final result is 124367.08433 with a remainder of 0.000305.
