724978 ÷ 39 
Our goal is to divide 724978 by 39.

Let's proceed to step 1:
When dividing 7 by 39, we get 0 with 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.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 39

On to step 2:
39 can be fit into 72 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 39 from 72 leaves us with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 39

Let's proceed to step 3:
If we divide 334 by 39, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 312 from 334 leaves us with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 39

Step 4:
229 divided by 39 is 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 185.0
The remainder is 34 after subtracting 195 from 229.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 39

Advancing to step 5:
The number 39 fits into 347 8 times, leaving a remainder of 35.
The next digit of our result is 8. 
Result so far: 1858.0
Subtract 312 from 347 to get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 39

Step 6:
39 can be fit into 358 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 18589.0
Subtracting 351 from 358 leaves us 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.

Let's proceed to step 7:
70 divided by 39 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 18589.1
If we subtract 39 from 70, we get 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 8:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 18589.17
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 18589.179
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:
39 goes into 190 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 18589.1794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 18589.17948
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
When dividing 280 by 39, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 18589.179487
Subtracting 273 from 280 leaves us 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.

Let's proceed to step 13:
If we divide 70 by 39, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 18589.1794871
If we subtract 39 from 70, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
39 goes into 310 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 18589.17948717
If we subtract 273 from 310, we 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.

The quotient of the division is 18589.17948717, and the remainder is 3.7e-08.
