Let's divide 672991 by 39
Our goal is to divide 672991 by 39.

Step 1:
6 divided by 39 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 39

Moving on to step 2:
67 divided by 39 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
If we take 39 away from 67, we end up with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 39

Step 3:
If we divide 282 by 39, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 273 from 282 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 39

Step 4:
When dividing 99 by 39, we get 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtract 78 from 99 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 39

Let's proceed to step 5:
39 goes into 219 5 times with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 1725.0
The remainder is 24 after subtracting 195 from 219.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 39

Going ahead to step 6:
39 can be fit into 241 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 17256.0
If we subtract 234 from 241, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 39, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 17256.1
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.

Going ahead to step 8:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 17256.17
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
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: 17256.179
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 10:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 17256.1794
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
If we divide 340 by 39, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 17256.17948
Deduct 312 from 340 and we're left with 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 12:
39 can be fit into 280 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 17256.179487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
When dividing 70 by 39, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 17256.1794871
Subtracting 39 from 70 leaves us 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.

On to step 14:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 17256.17948717
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 17256.17948717, with a leftover of 3.7e-08.
