We look at the division of 123437 by 39 
We want to figure out the number of times 123437 can be divided by 39.

Advancing to step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 39

Let's proceed to step 2:
The number 39 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 39

Advancing to step 3:
39 can be fit into 123 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 117 from 123 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 39

Advancing to step 4:
64 divided by 39 is 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 25 after subtracting 39 from 64.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 39

Step 5:
39 can be fit into 253 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 316.0
Subtracting 234 from 253 leaves us with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 39

Moving on to step 6:
197 divided by 39 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 3165.0
The remainder is 2 after subtracting 195 from 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 39 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3165.0
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.

Going ahead to step 8:
200 divided by 39 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3165.05
If we subtract 195 from 200, we get 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 9:
When dividing 50 by 39, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 3165.051
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
110 divided by 39 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 3165.0512
Subtracting 78 from 110 leaves us with 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 11:
320 divided by 39 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3165.05128
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
80 divided by 39 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 3165.051282
Subtracting 78 from 80 leaves us 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.

Step 13:
20 divided by 39 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3165.051282
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
When dividing 200 by 39, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3165.05128205
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 3165.05128205 with a remainder of 5e-09.
