We're dividing 860691 by 7 
Our goal is to divide 860691 by 7.

Advancing to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 7

Advancing to step 2:
7 can be fit into 16 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 14 from 16 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 7

Moving on to step 3:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 122.0
The remainder is 6 after subtracting 14 from 20.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Advancing to step 4:
7 can be fit into 66 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1229.0
If we take 63 away from 66, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

Step 5:
The number 7 fits into 39 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 12295.0
If we subtract 35 from 39, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 7

Let's proceed to step 6:
7 can be fit into 41 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 122955.0
Deduct 35 from 41 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.

Moving on to step 7:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 122955.8
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.

On to step 8:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 122955.85
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.

Going ahead to step 9:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 122955.857
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.

Moving on to step 10:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 122955.8571
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.

Going ahead 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: 122955.85714
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.

Moving on to step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 122955.857142
Subtract 14 from 20 to 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.

Let's proceed to step 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 122955.8571428
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.

Going ahead to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 122955.85714285
Deduct 35 from 40 and we're left 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.

The final outcome is 122955.85714285, with a leftover of 5e-09.
