We divide 128470 by 7
We want to figure out the number of times 128470 can be divided by 7.

Moving on to step 1:
If we divide 1 by 7, we get 0 and 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 (2) from the dividend to 1 and continue with: 12 / 7

On to step 2:
7 goes into 12 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 7 from 12, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

Going ahead to step 3:
7 goes into 58 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 56 from 58, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 7

Moving on to step 4:
When dividing 24 by 7, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we subtract 21 from 24, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 7

Going ahead to step 5:
If we divide 37 by 7, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1835.0
Deduct 35 from 37 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

On to step 6:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 18352.0
Subtracting 14 from 20 leaves us 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.

Let's proceed to step 7:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 18352.8
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.

Step 8:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 18352.85
The remainder is 5 after subtracting 35 from 40.
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 9:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 18352.857
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.

On to step 10:
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: 18352.8571
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:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 18352.85714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 18352.857142
If we subtract 14 from 20, 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.

Moving on to step 13:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18352.8571428
If we take 56 away from 60, 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 14:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 18352.85714285
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.

Our division results in 18352.85714285 with a remaining 5e-09.
