We look at the division of 622420 by 7 
We're looking to find how many times 7 goes into 622420.

On to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 7

Moving on to step 2:
7 goes into 62 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 6 after subtracting 56 from 62.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 7

On to step 3:
If we divide 62 by 7, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtracting 56 from 62 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 7

Step 4:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 889.0
If we subtract 63 from 64, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

Step 5:
12 divided by 7 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 8891.0
Subtracting 7 from 12 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

Advancing to step 6:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 88917.0
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.

Advancing to step 7:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 88917.1
If we take 7 away from 10, 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.

Advancing to step 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 88917.14
If we take 28 away from 30, we end up 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.

Advancing to step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 88917.142
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.

Advancing to step 10:
If we divide 60 by 7, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 88917.1428
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.

Let's proceed to step 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 88917.14285
Subtract 35 from 40 to get 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 12:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 88917.142857
Subtract 49 from 50 to 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.

Step 13:
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: 88917.1428571
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 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 88917.14285714
If we take 28 away from 30, we end up 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.

After the division, we end up with 88917.14285714 and a remainder of 2e-09.
