We divide 12313037 by 81
Let's see how many times 81 fits into 12313037.

Let's proceed to step 1:
81 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 81

Going ahead to step 2:
81 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 81

Advancing to step 3:
When dividing 123 by 81, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 123, we end up with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 81

On to step 4:
The number 81 fits into 421 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 16 after subtracting 405 from 421.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 81

Advancing to step 5:
When dividing 163 by 81, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Deduct 162 from 163 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 81

Step 6:
10 divided by 81 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1520.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 81

Let's proceed to step 7:
If we divide 103 by 81, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 15201.0
Deduct 81 from 103 and we're left with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 81

Advancing to step 8:
If we divide 227 by 81, we get 2 and a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 152012.0
If we take 162 away from 227, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
81 goes into 650 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 152012.8
If we take 648 away from 650, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 81, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 152012.8
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 152012.802
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
When dividing 380 by 81, we get 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 152012.8024
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
When dividing 560 by 81, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 152012.80246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
If we divide 740 by 81, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 152012.802469
Subtracting 729 from 740 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 15:
81 can be fit into 110 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 152012.8024691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 16:
When dividing 290 by 81, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 152012.80246913
Subtract 243 from 290 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 152012.80246913, with a leftover of 4.7e-08.
