We divide 51553927 by 407
We want to divide 51553927 by 407.

Advancing to step 1:
5 divided by 407 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.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 407

Let's proceed to step 2:
51 divided by 407 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 407

Moving on to step 3:
407 can be fit into 515 1 times, resulting in a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 407 from 515 to get 108.
Append the next digit (5) from the dividend to 108 and continue with: 1085 / 407

On to step 4:
The number 407 fits into 1085 2 times, leaving a remainder of 271.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 814 from 1085 leaves us with 271.
Grab the next digit (3) from the dividend, add it to 271, then carry on: 2713 / 407

Advancing to step 5:
407 can be fit into 2713 6 times, resulting in a remainder of 271.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 2442 from 2713 and we're left with 271.
Take the next digit (9) from the dividend and append it to 271, then repeat: 2719 / 407

Advancing to step 6:
407 goes into 2719 6 times with a remainder of 277.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
The remainder is 277 after subtracting 2442 from 2719.
Fetch the next digit (2) from the dividend, attach it to 277 and continue: 2772 / 407

Going ahead to step 7:
407 goes into 2772 6 times with a remainder of 330.
Use 6 as the next digit of our solution. 
Result so far: 12666.0
If we subtract 2442 from 2772, we get 330.
Bring next digit (7) of the dividend behind the 330 and repeat the process: 3307 / 407

Let's proceed to step 8:
407 goes into 3307 8 times with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 126668.0
If we take 3256 away from 3307, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
When dividing 510 by 407, we get 1 with a remainder of 103.
The next digit of our result is 1. 
Result so far: 126668.1
Subtracting 407 from 510 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 10:
When dividing 1030 by 407, we get 2 with a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 126668.12
If we subtract 814 from 1030, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 11:
If we divide 2160 by 407, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 126668.125
Subtracting 2035 from 2160 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
The number 407 fits into 1250 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 126668.1253
If we subtract 1221 from 1250, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
If we divide 290 by 407, we get 0 and a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 126668.1253
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
2900 divided by 407 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 126668.125307
Subtract 2849 from 2900 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 15:
510 divided by 407 is 1 with a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 126668.1253071
The remainder is 103 after subtracting 407 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 16:
The number 407 fits into 1030 2 times, leaving a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 126668.12530712
If we take 814 away from 1030, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 126668.12530712 with a remainder of 2.16e-07.
