We look at the division of 872486 by 7 
Let's see how many times 7 fits into 872486.

Going ahead to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

Let's proceed to step 2:
When dividing 17 by 7, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 14 from 17 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 7

Going ahead to step 3:
7 goes into 32 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtracting 28 from 32 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 7

Step 4:
If we divide 44 by 7, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1246.0
Deduct 42 from 44 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 7

Advancing to step 5:
7 can be fit into 28 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12464.0
If we take 28 away from 28, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 7

Moving on to step 6:
When dividing 6 by 7, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 124640.0
If we take 0 away from 6, we end up 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.

Going ahead to step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 124640.8
The remainder is 4 after subtracting 56 from 60.
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:
7 goes into 40 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 124640.85
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 9:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 124640.857
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.

Let's proceed to step 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 124640.8571
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.

Advancing to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 124640.85714
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.

Going ahead to step 12:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 124640.857142
Deduct 14 from 20 and we're left 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.

Step 13:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 124640.8571428
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.

Let's proceed to step 14:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 124640.85714285
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.

In conclusion, the division gives 124640.85714285 with a balance of 5e-09.
