Let's divide 404129 by 51
We want to figure out the number of times 404129 can be divided by 51.

Advancing to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 51

Advancing to step 2:
40 divided by 51 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 51

Moving on to step 3:
51 goes into 404 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 357 from 404 and we're left with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 51

Let's proceed to step 4:
51 can be fit into 471 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 459 from 471 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 51

Moving on to step 5:
The number 51 fits into 122 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 792.0
Subtracting 102 from 122 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 51

Moving on to step 6:
When dividing 209 by 51, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 7924.0
The remainder is 5 after subtracting 204 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7924.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 51, we get 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 7924.09
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
410 divided by 51 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7924.098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7924.098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 51, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 7924.09803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
51 goes into 470 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 7924.098039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
When dividing 110 by 51, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7924.0980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 7924.09803921
If we subtract 51 from 80, 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.

The quotient of the division is 7924.09803921, and the remainder is 2.9e-08.
