We look at the division of 427780 by 51 
We want to divide 427780 by 51.

Moving on to step 1:
51 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 51

Moving on to step 2:
If we divide 42 by 51, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 51

Going ahead to step 3:
When dividing 427 by 51, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 19 after subtracting 408 from 427.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 51

Step 4:
The number 51 fits into 197 3 times, leaving a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 44 after subtracting 153 from 197.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 51

Going ahead to step 5:
448 divided by 51 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 838.0
Deduct 408 from 448 and we're left with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 51

On to step 6:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 8387.0
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8387.8
Subtracting 408 from 430 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
When dividing 220 by 51, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8387.84
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
If we divide 160 by 51, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 8387.843
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 8387.8431
Deduct 51 from 70 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.

Advancing to step 11:
190 divided by 51 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 8387.84313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 8387.843137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
When dividing 130 by 51, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 8387.8431372
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
When dividing 280 by 51, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 8387.84313725
Subtract 255 from 280 to 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.

The final outcome is 8387.84313725, with a leftover of 2.5e-08.
