We're dividing 689590 by 39 
Let's see how many times 39 fits into 689590.

Advancing to step 1:
The number 39 fits into 6 0 times, leaving 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.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 39

Moving on to step 2:
68 divided by 39 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 39 from 68 and we're left with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 39

Going ahead to step 3:
The number 39 fits into 299 7 times, leaving a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 273 from 299 leaves us with 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 39

Advancing to step 4:
When dividing 265 by 39, we get 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Subtracting 234 from 265 leaves us with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 39

Advancing to step 5:
39 can be fit into 319 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1768.0
If we take 312 away from 319, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 39

Moving on to step 6:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 17681.0
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.

On to step 7:
310 divided by 39 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 17681.7
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.

Advancing to step 8:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 17681.79
If we subtract 351 from 370, we get 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 9:
190 divided by 39 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 17681.794
Deduct 156 from 190 and we're left 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.

Step 10:
If we divide 340 by 39, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 17681.7948
If we subtract 312 from 340, we get 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 11:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 17681.79487
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 12:
If we divide 70 by 39, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 17681.794871
Deduct 39 from 70 and we're left 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 13:
When dividing 310 by 39, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 17681.7948717
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.

Moving on to step 14:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 17681.79487179
Subtracting 351 from 370 leaves us 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.

After the division, we end up with 17681.79487179 and a remainder of 1.9e-08.
