We're dividing 12715171 by 198 
We want to divide 12715171 by 198.

Going ahead to step 1:
1 divided by 198 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 198

Going ahead to step 2:
12 divided by 198 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 198

Let's proceed to step 3:
If we divide 127 by 198, we get 0 and a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 127 leaves us with 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 198

On to step 4:
The number 198 fits into 1271 6 times, leaving a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 83 after subtracting 1188 from 1271.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 198

Let's proceed to step 5:
198 goes into 835 4 times with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 43 after subtracting 792 from 835.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 198

On to step 6:
198 goes into 431 2 times with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 642.0
Subtract 396 from 431 to get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 198

Let's proceed to step 7:
198 can be fit into 357 1 times, resulting in a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 6421.0
The remainder is 159 after subtracting 198 from 357.
Grab the next digit (1) from the dividend, add it to 159, then carry on: 1591 / 198

Advancing to step 8:
198 goes into 1591 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 64218.0
Subtracting 1584 from 1591 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 198, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 64218.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
When dividing 700 by 198, we get 3 with a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 64218.03
If we take 594 away from 700, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 11:
1060 divided by 198 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 64218.035
If we subtract 990 from 1060, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
The number 198 fits into 700 3 times, leaving a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 64218.0353
Subtracting 594 from 700 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
The number 198 fits into 1060 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 64218.03535
Deduct 990 from 1060 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
The number 198 fits into 700 3 times, leaving a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 64218.035353
Subtracting 594 from 700 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 15:
If we divide 1060 by 198, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 64218.0353535
The remainder is 70 after subtracting 990 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
The number 198 fits into 700 3 times, leaving a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 64218.03535353
If we subtract 594 from 700, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 64218.03535353 with a remaining 1.06e-07.
