We divide 107421 by 81
Let's see how many times 81 fits into 107421.

Going ahead to step 1:
1 divided by 81 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 81

Advancing to step 2:
The number 81 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 81

Let's proceed to step 3:
81 can be fit into 107 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 107 to get 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 81

Let's proceed to step 4:
If we divide 264 by 81, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 243 from 264, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 81

Moving on to step 5:
When dividing 212 by 81, we get 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Deduct 162 from 212 and we're left with 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 81

Advancing to step 6:
81 goes into 501 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 1326.0
If we take 486 away from 501, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
81 goes into 150 1 times with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 1326.1
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 8:
81 can be fit into 690 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 1326.18
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1326.185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 81 is 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 1326.1851
If we take 81 away from 150, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
When dividing 690 by 81, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 1326.18518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
When dividing 420 by 81, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1326.185185
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
When dividing 150 by 81, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1326.1851851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 14:
81 can be fit into 690 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 1326.18518518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 1326.18518518, with a leftover of 4.2e-08.
