Let's divide 857608 by 7
We want to divide 857608 by 7.

Going ahead to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 7 from 8, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 7

Advancing to step 2:
15 divided by 7 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 14 away from 15, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 7

Moving on to step 3:
7 can be fit into 17 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 14 from 17 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 7

Advancing to step 4:
7 can be fit into 36 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
Deduct 35 from 36 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 7

Step 5:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 12251.0
The remainder is 3 after subtracting 7 from 10.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 7

Going ahead to step 6:
38 divided by 7 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 122515.0
Subtract 35 from 38 to get 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 7:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 122515.4
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.

Moving on to step 8:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 122515.42
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.

Advancing to step 9:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 122515.428
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.

On to step 10:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 122515.4285
Subtracting 35 from 40 leaves us 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.

Let's proceed to step 11:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 122515.42857
Subtracting 49 from 50 leaves us 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.

Advancing to step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 122515.428571
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.

Advancing to step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 122515.4285714
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.

Step 14:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 122515.42857142
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.

After the division, we end up with 122515.42857142 and a remainder of 6e-09.
