Let's divide 690880 by 39
We want to figure out the number of times 690880 can be divided by 39.

Advancing to step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 39

Step 2:
The number 39 fits into 69 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 69, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 39

Advancing to step 3:
39 goes into 300 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 273 from 300 to get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 39

Going ahead to step 4:
278 divided by 39 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Deduct 273 from 278 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 39

Step 5:
39 can be fit into 58 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1771.0
If we subtract 39 from 58, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 39

Advancing to step 6:
39 goes into 190 4 times with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 17714.0
If we subtract 156 from 190, we 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.

On to step 7:
39 goes into 340 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 17714.8
Subtracting 312 from 340 leaves us 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.

Step 8:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 17714.87
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.

Going ahead to step 9:
When dividing 70 by 39, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 17714.871
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.

On to step 10:
The number 39 fits into 310 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 17714.8717
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.

Step 11:
If we divide 370 by 39, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 17714.87179
If we take 351 away from 370, we end up 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.

Step 12:
190 divided by 39 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 17714.871794
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.

Going ahead to step 13:
39 goes into 340 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 17714.8717948
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.

Step 14:
280 divided by 39 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 17714.87179487
Deduct 273 from 280 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.

In conclusion, the division gives 17714.87179487 with a balance of 7e-09.
