Let's divide 672138 by 39
Our goal is to divide 672138 by 39.

Going ahead to step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 39

Advancing to step 2:
When dividing 67 by 39, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 39 from 67 and we're left with 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 39

Going ahead to step 3:
39 goes into 282 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 273 from 282 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 39

Moving on to step 4:
39 can be fit into 91 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtracting 78 from 91 leaves us with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 39

Advancing to step 5:
When dividing 133 by 39, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 1723.0
If we take 117 away from 133, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 39

Let's proceed to step 6:
The number 39 fits into 168 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17234.0
The remainder is 12 after subtracting 156 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
39 goes into 120 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 17234.3
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.

Going ahead to step 8:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 17234.3
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 17234.307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
When dividing 270 by 39, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 17234.3076
Subtracting 234 from 270 leaves us 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 11:
If we divide 360 by 39, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 17234.30769
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.

Step 12:
90 divided by 39 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 17234.307692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 17234.3076923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
When dividing 30 by 39, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 17234.3076923
Deduct 0 from 30 and we're left 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.

The final outcome is 17234.3076923, with a leftover of 3e-08.
