We divide 978790 by 39
We're looking to find how many times 39 goes into 978790.

On to step 1:
The number 39 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 39

On to step 2:
When dividing 97 by 39, we get 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 78 from 97 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 39

Let's proceed to step 3:
39 can be fit into 198 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 195 from 198 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 39

Going ahead to step 4:
When dividing 37 by 39, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 39

Let's proceed to step 5:
39 can be fit into 379 9 times, resulting in a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 2509.0
If we subtract 351 from 379, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 39

Advancing to step 6:
39 goes into 280 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 25097.0
If we subtract 273 from 280, we get 7.
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 7:
When dividing 70 by 39, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 25097.1
Subtract 39 from 70 to 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.

Going ahead to step 8:
If we divide 310 by 39, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 25097.17
Deduct 273 from 310 and we're left 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.

On to step 9:
370 divided by 39 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 25097.179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
39 goes into 190 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 25097.1794
If we take 156 away from 190, we end up 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.

Let's proceed to step 11:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 25097.17948
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.

On to step 12:
The number 39 fits into 280 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 25097.179487
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.

Advancing to step 13:
39 goes into 70 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 25097.1794871
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.

Going ahead to step 14:
If we divide 310 by 39, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 25097.17948717
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.

The final result is 25097.17948717 with a remainder of 3.7e-08.
