Let's divide 51550501 by 407
We want to divide 51550501 by 407.

On to step 1:
5 divided by 407 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 407

Advancing to step 2:
51 divided by 407 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 407

Step 3:
When dividing 515 by 407, we get 1 with a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 407 away from 515, we end up with 108.
Include the next digit (5) from the dividend after 108, then repeat: 1085 / 407

Going ahead to step 4:
If we divide 1085 by 407, we get 2 and a remainder of 271.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 814 from 1085, we get 271.
Append the next digit (0) from the dividend to 271 and continue with: 2710 / 407

Advancing to step 5:
The number 407 fits into 2710 6 times, leaving a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtracting 2442 from 2710 leaves us with 268.
Fetch the next digit (5) from the dividend, attach it to 268 and continue: 2685 / 407

Let's proceed to step 6:
The number 407 fits into 2685 6 times, leaving a remainder of 243.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
Deduct 2442 from 2685 and we're left with 243.
Take the next digit (0) from the dividend and append it to 243, then repeat: 2430 / 407

On to step 7:
The number 407 fits into 2430 5 times, leaving a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 12665.0
If we take 2035 away from 2430, we end up with 395.
Take the next digit (1) from the dividend and append it to 395, then repeat: 3951 / 407

Going ahead to step 8:
When dividing 3951 by 407, we get 9 with a remainder of 288.
Record the quotient 9 as the next digit in the result. 
Result so far: 126659.0
If we subtract 3663 from 3951, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 9:
The number 407 fits into 2880 7 times, leaving a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 126659.7
The remainder is 31 after subtracting 2849 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
When dividing 310 by 407, we get 0 with a remainder of 310.
The next digit of our result is 0. 
Result so far: 126659.7
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 11:
When dividing 3100 by 407, we get 7 with a remainder of 251.
The number 7 becomes the next digit in our result. 
Result so far: 126659.707
Deduct 2849 from 3100 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 12:
2510 divided by 407 is 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 126659.7076
If we take 2442 away from 2510, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 13:
When dividing 680 by 407, we get 1 with a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 126659.70761
Subtract 407 from 680 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 14:
The number 407 fits into 2730 6 times, leaving a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 126659.707616
If we subtract 2442 from 2730, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 15:
If we divide 2880 by 407, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 126659.7076167
Subtracting 2849 from 2880 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 16:
407 goes into 310 0 times with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 126659.7076167
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 126659.7076167 with a balance of 3.1e-07.
