83690728 divided by 198 
We want to divide 83690728 by 198.

Let's proceed to step 1:
8 divided by 198 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 198

Advancing to step 2:
198 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 198

Moving on to step 3:
If we divide 836 by 198, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 792 from 836, we get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 198

Going ahead to step 4:
198 goes into 449 2 times with a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 396 from 449 to get 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 198

Moving on to step 5:
198 can be fit into 530 2 times, resulting in a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 422.0
If we subtract 396 from 530, we get 134.
Include the next digit (7) from the dividend after 134, then repeat: 1347 / 198

On to step 6:
When dividing 1347 by 198, we get 6 with a remainder of 159.
Record the quotient 6 as the next digit in the result. 
Result so far: 4226.0
If we take 1188 away from 1347, we end up with 159.
Grab the next digit (2) from the dividend, add it to 159, then carry on: 1592 / 198

Step 7:
If we divide 1592 by 198, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 42268.0
The remainder is 8 after subtracting 1584 from 1592.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 198

Advancing to step 8:
The number 198 fits into 88 0 times, leaving a remainder of 88.
The next digit of our result is 0. 
Result so far: 422680.0
Deduct 0 from 88 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
When dividing 880 by 198, we get 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 422680.4
Subtract 792 from 880 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
The number 198 fits into 880 4 times, leaving a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 422680.44
If we take 792 away from 880, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 422680.44 and a remainder of 0.088.
