We're dividing 120918 by 39 
We want to figure out the number of times 120918 can be divided by 39.

Step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 39

Moving on to step 2:
39 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 39

Advancing to step 3:
If we divide 120 by 39, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
If we take 117 away from 120, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 39

Let's proceed to step 4:
39 divided by 39 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 39 from 39 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 39

Step 5:
When dividing 1 by 39, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 310.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 39

Step 6:
When dividing 18 by 39, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 3100.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
39 goes into 180 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3100.4
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
240 divided by 39 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3100.46
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 39, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 3100.461
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3100.4615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 3100.46153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
If we divide 330 by 39, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 3100.461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
When dividing 180 by 39, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 3100.4615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
39 goes into 240 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3100.46153846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 3100.46153846 with a remainder of 6e-09.
