We divide 689456 by 39
We want to figure out the number of times 689456 can be divided by 39.

On to step 1:
When dividing 6 by 39, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 39

Moving on to step 2:
39 goes into 68 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
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

On to step 3:
The number 39 fits into 299 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 273 from 299 leaves us with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 39

On to step 4:
The number 39 fits into 264 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 176.0
If we subtract 234 from 264, we get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 39

Advancing to step 5:
The number 39 fits into 305 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 1767.0
If we subtract 273 from 305, we get 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 39

Advancing to step 6:
When dividing 326 by 39, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 17678.0
Subtracting 312 from 326 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 39, we get 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 17678.3
Subtract 117 from 140 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 17678.35
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
When dividing 350 by 39, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 17678.358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 17678.3589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
When dividing 290 by 39, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 17678.35897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 17678.358974
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
140 divided by 39 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 17678.3589743
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
39 goes into 230 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17678.35897435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 17678.35897435, with a leftover of 3.5e-08.
