We're dividing 109115 by 7 
We want to figure out the number of times 109115 can be divided by 7.

Let's proceed to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 7

Step 2:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 7 from 10 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 7

Let's proceed to step 3:
39 divided by 7 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 35 from 39 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

On to step 4:
If we divide 41 by 7, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we subtract 35 from 41, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 7

On to step 5:
The number 7 fits into 61 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 1558.0
Deduct 56 from 61 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 7

Going ahead to step 6:
7 goes into 55 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 15587.0
If we subtract 49 from 55, 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 7:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 15587.8
Subtract 56 from 60 to 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 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15587.85
If we take 35 away from 40, we end up 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.

On to step 9:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 15587.857
Subtract 49 from 50 to 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.

Advancing to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 15587.8571
If we subtract 7 from 10, we 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.

Let's proceed to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 15587.85714
If we subtract 28 from 30, we get 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 12:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 15587.857142
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.

Going ahead to step 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15587.8571428
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 14:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15587.85714285
Subtract 35 from 40 to 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.

Our division results in 15587.85714285 with a remaining 5e-09.
