We're dividing 651873 by 39 
Let's see how many times 39 fits into 651873.

Going ahead to step 1:
39 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 39

Advancing to step 2:
39 can be fit into 65 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 39 away from 65, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 39

On to step 3:
If we divide 261 by 39, we get 6 and a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 234 from 261, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 39

Going ahead to step 4:
The number 39 fits into 278 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 167.0
Deduct 273 from 278 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 39

Step 5:
The number 39 fits into 57 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1671.0
If we take 39 away from 57, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 39

Advancing to step 6:
183 divided by 39 is 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 16714.0
Subtract 156 from 183 to get 27.
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 7:
The number 39 fits into 270 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 16714.6
The remainder is 36 after subtracting 234 from 270.
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 8:
If we divide 360 by 39, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 16714.69
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.

Advancing to step 9:
39 goes into 90 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 16714.692
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.

Moving on to step 10:
If we divide 120 by 39, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 16714.6923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 16714.6923
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 12:
When dividing 300 by 39, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 16714.692307
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 13:
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: 16714.6923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
If we divide 360 by 39, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 16714.69230769
If we subtract 351 from 360, we 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.

The final result is 16714.69230769 with a remainder of 9e-09.
