We divide 857831 by 7
Let's see how many times 7 fits into 857831.

Let's proceed to step 1:
7 goes into 8 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 7

Advancing to step 2:
When dividing 15 by 7, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 1 after subtracting 14 from 15.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

On to step 3:
7 can be fit into 17 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 14 from 17 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 7

Let's proceed to step 4:
If we divide 38 by 7, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 1225.0
Subtract 35 from 38 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 7

Let's proceed to step 5:
33 divided by 7 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 12254.0
Subtracting 28 from 33 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 7

Step 6:
If we divide 51 by 7, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 122547.0
Subtract 49 from 51 to 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.

Step 7:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 122547.2
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.

Going ahead to step 8:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 122547.28
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.

Going ahead to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 122547.285
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.

Moving on to step 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 122547.2857
Deduct 49 from 50 and we're left with 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 11:
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: 122547.28571
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.

Moving on to step 12:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 122547.285714
Subtract 28 from 30 to 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.

Step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 122547.2857142
The remainder is 6 after subtracting 14 from 20.
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 14:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 122547.28571428
Deduct 56 from 60 and we're left 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.

In conclusion, the division gives 122547.28571428 with a balance of 4e-09.
