We look at the division of 407356 by 51 
We want to figure out the number of times 407356 can be divided by 51.

Step 1:
When dividing 4 by 51, we get 0 with 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.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 51

On to step 2:
51 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 51

Step 3:
The number 51 fits into 407 7 times, leaving a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 50 after subtracting 357 from 407.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 51

Advancing to step 4:
When dividing 503 by 51, we get 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 459 from 503 leaves us with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 51

Step 5:
The number 51 fits into 445 8 times, leaving a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 798.0
Deduct 408 from 445 and we're left with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 51

Moving on to step 6:
When dividing 376 by 51, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7987.0
Deduct 357 from 376 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 51 fits into 190 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 7987.3
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
When dividing 370 by 51, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7987.37
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 51 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7987.372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 51, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 7987.3725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
The number 51 fits into 250 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 7987.37254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 7987.372549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
If we divide 10 by 51, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7987.372549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
51 can be fit into 100 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 7987.37254901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 7987.37254901 with a balance of 4.9e-08.
