86270164 divided by 7 
Let's see how many times 7 fits into 86270164.

Advancing to step 1:
When dividing 8 by 7, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 7 from 8, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 7

If we divide 16 by 7, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 2 after subtracting 14 from 16.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 7

Going ahead to step 3:
7 goes into 22 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 21 away from 22, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 7

Going ahead to step 4:
If we divide 17 by 7, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1232.0
Subtract 14 from 17 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 7

Advancing to step 5:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 12324.0
If we take 28 away from 30, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 7

Let's proceed to step 6:
21 divided by 7 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 123243.0
The remainder is 0 after subtracting 21 from 21.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 7

Let's proceed to step 7:
If we divide 6 by 7, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1232430.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 7

Moving on to step 8:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 12324309.0
The remainder is 1 after subtracting 63 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 12324309.1
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 12324309.14
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.

Moving on to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12324309.142
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.

Moving on to step 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12324309.1428
Subtracting 56 from 60 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.

Advancing to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 12324309.14285
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.

Let's proceed to step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 12324309.142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 15:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 12324309.1428571
Subtracting 7 from 10 leaves us 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.

On to step 16:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 12324309.14285714
Deduct 28 from 30 and we're left 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.

The quotient of the division is 12324309.14285714, and the remainder is 2e-09.
