351979 divided by 39 
Our goal is to divide 351979 by 39.

Step 1:
3 divided by 39 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 39

Going ahead to step 2:
The number 39 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 39

Moving on to step 3:
The number 39 fits into 351 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 351 from 351 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 39

On to step 4:
If we divide 9 by 39, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 90.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 39

Let's proceed to step 5:
39 goes into 97 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 902.0
Deduct 78 from 97 and we're left with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 39

Moving on to step 6:
199 divided by 39 is 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 9025.0
If we subtract 195 from 199, 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 7:
If we divide 40 by 39, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 9025.1
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 39, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9025.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 39 fits into 100 2 times, leaving a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 9025.102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 9025.1025
Subtract 195 from 220 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
The number 39 fits into 250 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9025.10256
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.

On to step 12:
When dividing 160 by 39, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 9025.102564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
39 can be fit into 40 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 9025.1025641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 9025.1025641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 9025.1025641 with a remainder of 1e-08.
