Let's divide 312453 by 39
Our goal is to divide 312453 by 39.

Moving on to step 1:
39 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 39

Step 2:
39 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 39

On to step 3:
39 can be fit into 312 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 312 from 312 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 39

On to step 4:
39 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 39

Moving on to step 5:
When dividing 45 by 39, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 801.0
If we take 39 away from 45, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 39

Going ahead to step 6:
The number 39 fits into 63 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 8011.0
Deduct 39 from 63 and we're left 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.

On to step 7:
240 divided by 39 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 8011.6
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 8011.61
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
39 goes into 210 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8011.615
Deduct 195 from 210 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.

Moving on to step 10:
39 goes into 150 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 8011.6153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 11:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 8011.61538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
180 divided by 39 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 8011.615384
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
If we divide 240 by 39, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 8011.6153846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 8011.61538461
Subtract 39 from 60 to 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.

The quotient of the division is 8011.61538461, and the remainder is 2.1e-08.
