753420 ÷ 39 
We want to figure out the number of times 753420 can be divided by 39.

Step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 39

Let's proceed to step 2:
75 divided by 39 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 39 from 75 leaves us with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 39

Going ahead to step 3:
39 goes into 363 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 351 from 363, we get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 39

Moving on to step 4:
39 goes into 124 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 193.0
The remainder is 7 after subtracting 117 from 124.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 39

Step 5:
The number 39 fits into 72 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1931.0
If we take 39 away from 72, we end up with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 39

Going ahead to step 6:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 19318.0
Subtract 312 from 330 to 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.

Going ahead to step 7:
When dividing 180 by 39, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 19318.4
Subtracting 156 from 180 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 8:
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: 19318.46
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
60 divided by 39 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 19318.461
Subtracting 39 from 60 leaves us 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.

Let's proceed to step 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 19318.4615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
The number 39 fits into 150 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 19318.46153
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.

Moving on to step 12:
When dividing 330 by 39, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 19318.461538
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.

Advancing to step 13:
If we divide 180 by 39, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 19318.4615384
Deduct 156 from 180 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.

Step 14:
240 divided by 39 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 19318.46153846
Subtracting 234 from 240 leaves us 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.

The final result is 19318.46153846 with a remainder of 6e-09.
