We're dividing 109170 by 7 
Our goal is to divide 109170 by 7.

Going ahead to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 7

Let's proceed to step 2:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 7 from 10 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 7

On to step 3:
7 can be fit into 39 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 35 away from 39, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 7

Moving on to step 4:
41 divided by 7 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 155.0
The remainder is 6 after subtracting 35 from 41.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 7

On to step 5:
67 divided by 7 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1559.0
If we take 63 away from 67, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 7

Advancing to step 6:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 15595.0
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 15595.7
If we take 49 away from 50, we end up 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 8:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 15595.71
Subtract 7 from 10 to 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.

On to step 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 15595.714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 15595.7142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
7 goes into 60 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 15595.71428
If we subtract 56 from 60, 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.

Advancing to step 12:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 15595.714285
Subtracting 35 from 40 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 15595.7142857
If we subtract 49 from 50, we get 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 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 15595.71428571
Deduct 7 from 10 and we're left 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.

The final result is 15595.71428571 with a remainder of 3e-09.
