Let's divide 121120 by 39
We want to divide 121120 by 39.

Let's proceed to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 39

On to step 2:
39 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 39

Let's proceed to step 3:
If we divide 121 by 39, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 117 from 121 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 39

Going ahead to step 4:
The number 39 fits into 41 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 31.0
If we take 39 away from 41, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 39

Going ahead to step 5:
39 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 310.0
If we take 0 away from 22, we end up with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 39

Moving on to step 6:
39 goes into 220 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3105.0
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 7:
250 divided by 39 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 3105.6
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3105.64
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 39, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3105.641
Subtracting 39 from 40 leaves us 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.

Moving on to step 10:
When dividing 10 by 39, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3105.641
The remainder is 10 after subtracting 0 from 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 11:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 3105.64102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
When dividing 220 by 39, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3105.641025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
250 divided by 39 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3105.6410256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 39 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 3105.64102564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 3105.64102564 with a remaining 4e-09.
