Let's divide 990207 by 39
We want to figure out the number of times 990207 can be divided by 39.

Step 1:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 39

On to step 2:
39 goes into 99 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 78 from 99 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 39

On to step 3:
The number 39 fits into 210 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 195 from 210, we get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 39

On to step 4:
The number 39 fits into 152 3 times, leaving a remainder of 35.
The next digit of our result is 3. 
Result so far: 253.0
Subtracting 117 from 152 leaves us with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 39

Step 5:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 2538.0
The remainder is 38 after subtracting 312 from 350.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 39

Let's proceed to step 6:
The number 39 fits into 387 9 times, leaving a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 25389.0
The remainder is 36 after subtracting 351 from 387.
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 7:
If we divide 360 by 39, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 25389.9
If we take 351 away from 360, we end up 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 8:
When dividing 90 by 39, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 25389.92
Subtracting 78 from 90 leaves us 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.

Advancing to step 9:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 25389.923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
30 divided by 39 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 25389.923
Subtracting 0 from 30 leaves us 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.

Moving on to step 11:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 25389.92307
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
When dividing 270 by 39, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 25389.923076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 25389.9230769
Subtract 351 from 360 to 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 14:
90 divided by 39 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 25389.92307692
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.

The final outcome is 25389.92307692, with a leftover of 1.2e-08.
