831638 divided by 7 
Let's see how many times 7 fits into 831638.

Step 1:
When dividing 8 by 7, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 7

Advancing to step 2:
When dividing 13 by 7, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 7 from 13 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 7

Step 3:
7 goes into 61 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Deduct 56 from 61 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Moving on to step 4:
56 divided by 7 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1188.0
The remainder is 0 after subtracting 56 from 56.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 7

Moving on to step 5:
7 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 11880.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 7

Advancing to step 6:
38 divided by 7 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 118805.0
If we take 35 away from 38, we end up 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 7:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 118805.4
Subtracting 28 from 30 leaves us 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.

Step 8:
20 divided by 7 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 118805.42
If we take 14 away from 20, 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.

On to step 9:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 118805.428
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 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 118805.4285
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.

Step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 118805.42857
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.

Going ahead to step 12:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 118805.428571
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.

On to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 118805.4285714
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.

On to step 14:
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: 118805.42857142
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.

The final result is 118805.42857142 with a remainder of 6e-09.
