We look at the division of 747249 by 39 
We want to figure out the number of times 747249 can be divided by 39.

Step 1:
39 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 39

Let's proceed to step 2:
74 divided by 39 is 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
If we take 39 away from 74, we end up with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 39

Step 3:
When dividing 357 by 39, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 351 from 357, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 39

Step 4:
When dividing 62 by 39, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 191.0
Deduct 39 from 62 and we're left with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 39

Advancing to step 5:
If we divide 234 by 39, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1916.0
Subtract 234 from 234 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 39

Step 6:
39 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 19160.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 19160.2
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 39, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 19160.23
The remainder is 3 after subtracting 117 from 120.
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 9:
30 divided by 39 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 19160.23
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 39, we get 7 and a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 19160.2307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
39 goes into 270 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 19160.23076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 39, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 19160.230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
90 divided by 39 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 19160.2307692
Subtract 78 from 90 to 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 14:
When dividing 120 by 39, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 19160.23076923
If we take 117 away from 120, we end up 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.

The quotient of the division is 19160.23076923, and the remainder is 3e-09.
