We divide 80939400 by 51
Our goal is to divide 80939400 by 51.

Advancing to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 51

On to step 2:
The number 51 fits into 80 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 29 after subtracting 51 from 80.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 51

Let's proceed to step 3:
51 can be fit into 299 5 times, resulting in a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 44 after subtracting 255 from 299.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 51

Going ahead to step 4:
When dividing 443 by 51, we get 8 with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtracting 408 from 443 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 51

Going ahead to step 5:
The number 51 fits into 359 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1587.0
Subtracting 357 from 359 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 51

Let's proceed to step 6:
When dividing 24 by 51, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 15870.0
The remainder is 24 after subtracting 0 from 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 51

Let's proceed to step 7:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 158704.0
Deduct 204 from 240 and we're left with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 51

Moving on to step 8:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 1587047.0
Subtracting 357 from 360 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 1587047.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 51 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1587047.05
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 1587047.058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
420 divided by 51 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1587047.0588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1587047.0588 with a remainder of 0.00012.
