51198234 divided by 80 
We're looking to find how many times 80 goes into 51198234.

Step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 80

Going ahead to step 2:
When dividing 51 by 80, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 80

Going ahead to step 3:
If we divide 511 by 80, we get 6 and a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 31 after subtracting 480 from 511.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 80

Going ahead to step 4:
The number 80 fits into 319 3 times, leaving a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 240 from 319, we get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 80

On to step 5:
When dividing 798 by 80, we get 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 639.0
Subtracting 720 from 798 leaves us with 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 80

Advancing to step 6:
The number 80 fits into 782 9 times, leaving a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 6399.0
Deduct 720 from 782 and we're left with 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 80

Advancing to step 7:
80 goes into 623 7 times with a remainder of 63.
The next digit of our result is 7. 
Result so far: 63997.0
Subtract 560 from 623 to get 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 80

Advancing to step 8:
80 goes into 634 7 times with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 639977.0
If we subtract 560 from 634, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
The number 80 fits into 740 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 639977.9
If we take 720 away from 740, we end up 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.

Let's proceed to step 10:
If we divide 200 by 80, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 639977.92
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 639977.925
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 639977.925
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 639977.925
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 639977.925 with a remaining 0.0.
