We divide 12369057 by 31
We're looking to find how many times 31 goes into 12369057.

On to step 1:
31 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
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 31

Let's proceed to step 2:
31 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 31

Advancing to step 3:
When dividing 123 by 31, we get 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 93 from 123 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 31

Moving on to step 4:
When dividing 306 by 31, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 279 from 306 leaves us with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 31

Let's proceed to step 5:
When dividing 279 by 31, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 399.0
Subtracting 279 from 279 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 31

Let's proceed to step 6:
When dividing 0 by 31, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3990.0
If we take 0 away from 0, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 31

Moving on to step 7:
31 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 39900.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 31

On to step 8:
If we divide 57 by 31, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 399001.0
If we subtract 31 from 57, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
260 divided by 31 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 399001.8
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 399001.83
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
The number 31 fits into 270 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 399001.838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
If we divide 220 by 31, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 399001.8387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
30 divided by 31 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 399001.8387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
31 can be fit into 300 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 399001.838709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 15:
When dividing 210 by 31, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 399001.8387096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 16:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 399001.83870967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 399001.83870967, with a leftover of 2.3e-08.
