91639371 divided by 198 
We're looking to find how many times 198 goes into 91639371.

Step 1:
When dividing 9 by 198, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 198

Let's proceed to step 2:
When dividing 91 by 198, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 198

Going ahead to step 3:
The number 198 fits into 916 4 times, leaving a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 124 after subtracting 792 from 916.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 198

On to step 4:
The number 198 fits into 1243 6 times, leaving a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 55 after subtracting 1188 from 1243.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 198

On to step 5:
198 can be fit into 559 2 times, resulting in a remainder of 163.
Put 2 as the next digit of the answer. 
Result so far: 462.0
Subtract 396 from 559 to get 163.
Include the next digit (3) from the dividend after 163, then repeat: 1633 / 198

Moving on to step 6:
198 can be fit into 1633 8 times, resulting in a remainder of 49.
The next digit of our result is 8. 
Result so far: 4628.0
Subtract 1584 from 1633 to get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 198

Going ahead to step 7:
198 goes into 497 2 times with a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 46282.0
If we take 396 away from 497, we end up with 101.
Grab the next digit (1) from the dividend, add it to 101, then carry on: 1011 / 198

Let's proceed to step 8:
198 goes into 1011 5 times with a remainder of 21.
The next digit of our result is 5. 
Result so far: 462825.0
If we take 990 away from 1011, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
198 goes into 210 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 462825.1
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
198 can be fit into 120 0 times, resulting in a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 462825.1
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
198 can be fit into 1200 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 462825.106
Deduct 1188 from 1200 and we're left 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.

On to step 12:
198 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 462825.106
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
198 can be fit into 1200 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 462825.10606
Deduct 1188 from 1200 and we're left 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.

Advancing to step 14:
When dividing 120 by 198, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 462825.10606
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
1200 divided by 198 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 462825.1060606
Subtract 1188 from 1200 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
198 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 462825.1060606
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 462825.1060606 with a remainder of 1.2e-07.
