Let's divide 686422 by 39
Let's see how many times 39 fits into 686422.

Let's proceed to step 1:
The number 39 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Moving on to step 2:
39 goes into 68 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 39 from 68, we get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 39

On to step 3:
39 goes into 296 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 273 from 296, we get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 39

Advancing to step 4:
234 divided by 39 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
The remainder is 0 after subtracting 234 from 234.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 39

Going ahead to step 5:
The number 39 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 1760.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 39

Let's proceed to step 6:
The number 39 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 17600.0
Deduct 0 from 22 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
39 goes into 220 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 17600.5
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
39 can be fit into 250 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 17600.56
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
160 divided by 39 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 17600.564
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
39 goes into 40 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 17600.5641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
10 divided by 39 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 17600.5641
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 39, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 17600.564102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
When dividing 220 by 39, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 17600.5641025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
39 can be fit into 250 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 17600.56410256
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 17600.56410256 and a remainder of 1.6e-08.
