We divide 198988 by 81
We want to divide 198988 by 81.

Step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 81

On to step 2:
If we divide 19 by 81, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 81

Let's proceed to step 3:
81 can be fit into 198 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 162 from 198 leaves us with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 81

On to step 4:
The number 81 fits into 369 4 times, leaving a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 324 from 369, we get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 81

Advancing to step 5:
81 goes into 458 5 times with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.0
If we take 405 away from 458, we end up with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 81

Let's proceed to step 6:
When dividing 538 by 81, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 2456.0
If we take 486 away from 538, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 2456.6
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 81, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 2456.64
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 81, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 2456.641
Deduct 81 from 160 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 10:
81 goes into 790 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 2456.6419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 11:
81 goes into 610 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 2456.64197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
If we divide 430 by 81, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2456.641975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
If we divide 250 by 81, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 2456.6419753
If we take 243 away from 250, we end up 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.

Let's proceed to step 14:
When dividing 70 by 81, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 2456.6419753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 2456.6419753 with a remainder of 7e-08.
