We're dividing 61981297 by 81 
We want to divide 61981297 by 81.

Step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 81

Step 2:
81 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 81

Going ahead to step 3:
If we divide 619 by 81, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 567 from 619 to get 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 81

On to step 4:
81 can be fit into 528 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtracting 486 from 528 leaves us with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 81

Step 5:
The number 81 fits into 421 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 765.0
Subtracting 405 from 421 leaves us with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 81

Going ahead to step 6:
If we divide 162 by 81, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 7652.0
If we take 162 away from 162, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 81

Let's proceed to step 7:
The number 81 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 76520.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 81

Moving on to step 8:
97 divided by 81 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 765201.0
If we take 81 away from 97, we end up 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.

Let's proceed to step 9:
160 divided by 81 is 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 765201.1
If we subtract 81 from 160, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
If we divide 790 by 81, we get 9 and a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 765201.19
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.

Let's proceed to step 11:
610 divided by 81 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 765201.197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 765201.1975
Subtracting 405 from 430 leaves us 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.

Let's proceed to step 13:
When dividing 250 by 81, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 765201.19753
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.

Moving on to step 14:
When dividing 70 by 81, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 765201.19753
If we take 0 away from 70, we end up 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.

On to step 15:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 765201.1975308
Subtracting 648 from 700 leaves us 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.

On to step 16:
If we divide 520 by 81, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 765201.19753086
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 765201.19753086 and a remainder of 3.4e-08.
