Let's divide 617900 by 7
We're looking to find how many times 7 goes into 617900.

On to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

Let's proceed to step 2:
7 can be fit into 61 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 56 from 61 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 7

On to step 3:
If we divide 57 by 7, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtract 56 from 57 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

On to step 4:
7 goes into 19 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 882.0
Subtract 14 from 19 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 7

Advancing to step 5:
7 goes into 50 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 8827.0
The remainder is 1 after subtracting 49 from 50.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 7

On to step 6:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 88271.0
If we subtract 7 from 10, we 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:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 88271.4
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.

Advancing to step 8:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 88271.42
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.

On to step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 88271.428
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 10:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 88271.4285
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.

On to step 11:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 88271.42857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 88271.428571
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 13:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 88271.4285714
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.

Let's proceed to step 14:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 88271.42857142
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.

Our division results in 88271.42857142 with a remaining 6e-09.
