We're dividing 404213 by 51 
Our goal is to divide 404213 by 51.

On to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 51

Step 2:
If we divide 40 by 51, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the 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:
If we divide 404 by 51, we get 7 and a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 357 from 404, we get 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 51

Step 4:
51 can be fit into 472 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 459 from 472 to get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 51

Advancing to step 5:
51 can be fit into 131 2 times, resulting in a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 792.0
Deduct 102 from 131 and we're left with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 51

Let's proceed to step 6:
When dividing 293 by 51, we get 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 7925.0
If we subtract 255 from 293, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
51 goes into 380 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 7925.7
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
51 goes into 230 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7925.74
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
If we divide 260 by 51, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7925.745
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
51 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 7925.745
If we take 0 away from 50, we end up 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.

Step 11:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 7925.74509
Subtract 459 from 500 to get 41.
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 12:
51 can be fit into 410 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7925.745098
Deduct 408 from 410 and we're left with 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 13:
When dividing 20 by 51, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7925.745098
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 51 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 7925.74509803
Deduct 153 from 200 and we're left 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.

The final result is 7925.74509803 with a remainder of 4.7e-08.
