Let's divide 77788536 by 198
We want to figure out the number of times 77788536 can be divided by 198.

On to step 1:
The number 198 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 198

Let's proceed to step 2:
77 divided by 198 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 198

On to step 3:
198 can be fit into 777 3 times, resulting in a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 594 from 777, we get 183.
Fetch the next digit (8) from the dividend, attach it to 183 and continue: 1838 / 198

Advancing to step 4:
When dividing 1838 by 198, we get 9 with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 56 after subtracting 1782 from 1838.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 198

On to step 5:
The number 198 fits into 568 2 times, leaving a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 392.0
If we take 396 away from 568, we end up with 172.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 198

Moving on to step 6:
198 can be fit into 1725 8 times, resulting in a remainder of 141.
Record the quotient 8 as the next digit in the result. 
Result so far: 3928.0
The remainder is 141 after subtracting 1584 from 1725.
Append the next digit (3) from the dividend to 141 and continue with: 1413 / 198

Going ahead to step 7:
When dividing 1413 by 198, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 39287.0
If we subtract 1386 from 1413, we get 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 198

On to step 8:
198 goes into 276 1 times with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 392871.0
If we take 198 away from 276, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
198 can be fit into 780 3 times, resulting in a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 392871.3
Deduct 594 from 780 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
When dividing 1860 by 198, we get 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 392871.39
Subtracting 1782 from 1860 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
If we divide 780 by 198, we get 3 and a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 392871.393
Subtracting 594 from 780 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 12:
The number 198 fits into 1860 9 times, leaving a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 392871.3939
Subtract 1782 from 1860 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
780 divided by 198 is 3 with a remainder of 186.
The next digit of our result is 3. 
Result so far: 392871.39393
If we take 594 away from 780, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 14:
1860 divided by 198 is 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 392871.393939
Subtracting 1782 from 1860 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 15:
198 goes into 780 3 times with a remainder of 186.
The next digit of our result is 3. 
Result so far: 392871.3939393
Subtracting 594 from 780 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 16:
198 goes into 1860 9 times with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 392871.39393939
Subtracting 1782 from 1860 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 392871.39393939 with a balance of 7.8e-08.
