We divide 12348407 by 39
We want to divide 12348407 by 39.

Advancing to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 39

Step 2:
If we divide 12 by 39, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 39

Let's proceed to step 3:
39 can be fit into 123 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 117 from 123 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 39

Let's proceed to step 4:
The number 39 fits into 64 1 times, leaving a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 39 from 64 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 39

Step 5:
39 can be fit into 258 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
Deduct 234 from 258 and we're left with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 39

Advancing to step 6:
39 can be fit into 244 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 3166.0
If we take 234 away from 244, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 39

Moving on to step 7:
100 divided by 39 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 31662.0
If we take 78 away from 100, we end up with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 39

Let's proceed to step 8:
The number 39 fits into 227 5 times, leaving a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 316625.0
The remainder is 32 after subtracting 195 from 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 39, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 316625.8
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 39 fits into 80 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 316625.82
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
39 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 316625.82
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 316625.8205
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 316625.82051
Subtracting 39 from 50 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.

Going ahead to step 14:
39 goes into 110 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 316625.820512
Subtract 78 from 110 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 15:
320 divided by 39 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 316625.8205128
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 16:
39 can be fit into 80 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 316625.82051282
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 316625.82051282 and a remainder of 2e-09.
