We look at the division of 745648 by 39 
We want to figure out the number of times 745648 can be divided by 39.

Moving on to step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 39

Moving on to step 2:
When dividing 74 by 39, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 74, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 39

Step 3:
355 divided by 39 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 351 from 355 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 39

Moving on to step 4:
When dividing 46 by 39, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 191.0
If we subtract 39 from 46, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 39

Moving on to step 5:
39 can be fit into 74 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1911.0
Subtract 39 from 74 to get 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 39

Going ahead to step 6:
39 can be fit into 358 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 19119.0
Deduct 351 from 358 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 39 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 19119.1
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
39 goes into 310 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 19119.17
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
370 divided by 39 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 19119.179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 19119.1794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
When dividing 340 by 39, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 19119.17948
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 19119.179487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
39 can be fit into 70 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 19119.1794871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 19119.17948717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 19119.17948717 with a remainder of 3.7e-08.
