61728867 divided by 798 
We want to figure out the number of times 61728867 can be divided by 798.

Step 1:
798 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 798

Going ahead to step 2:
798 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 798

Step 3:
When dividing 617 by 798, we get 0 with a remainder of 617.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 617, we get 617.
Append the next digit (2) from the dividend to 617 and continue with: 6172 / 798

Going ahead to step 4:
If we divide 6172 by 798, we get 7 and a remainder of 586.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 5586 from 6172, we get 586.
Include the next digit (8) from the dividend after 586, then repeat: 5868 / 798

Step 5:
If we divide 5868 by 798, we get 7 and a remainder of 282.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 5586 from 5868 and we're left with 282.
Bring next digit (8) of the dividend behind the 282 and repeat the process: 2828 / 798

Going ahead to step 6:
When dividing 2828 by 798, we get 3 with a remainder of 434.
Write down 3 as next digit of the result. 
Result so far: 773.0
If we take 2394 away from 2828, we end up with 434.
Grab the next digit (6) from the dividend, add it to 434, then carry on: 4346 / 798

On to step 7:
4346 divided by 798 is 5 with a remainder of 356.
The next digit of our result is 5. 
Result so far: 7735.0
Deduct 3990 from 4346 and we're left with 356.
Append the next digit (7) from the dividend to 356 and continue with: 3567 / 798

On to step 8:
The number 798 fits into 3567 4 times, leaving a remainder of 375.
Record the quotient 4 as the next digit in the result. 
Result so far: 77354.0
The remainder is 375 after subtracting 3192 from 3567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 9:
When dividing 3750 by 798, we get 4 with a remainder of 558.
The number 4 becomes the next digit in our result. 
Result so far: 77354.4
Subtract 3192 from 3750 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 10:
798 can be fit into 5580 6 times, resulting in a remainder of 792.
Use 6 as the next digit of our solution. 
Result so far: 77354.46
The remainder is 792 after subtracting 4788 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Step 11:
798 can be fit into 7920 9 times, resulting in a remainder of 738.
Put 9 as the next digit of the answer. 
Result so far: 77354.469
If we take 7182 away from 7920, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

On to step 12:
If we divide 7380 by 798, we get 9 and a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 77354.4699
The remainder is 198 after subtracting 7182 from 7380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The quotient of the division is 77354.4699, and the remainder is 0.00198.
