Let's divide 621220 by 7
We want to figure out the number of times 621220 can be divided by 7.

Step 1:
6 divided by 7 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 7

Going ahead to step 2:
When dividing 62 by 7, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 56 from 62 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 7

Going ahead to step 3:
When dividing 61 by 7, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we take 56 away from 61, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 7

Going ahead to step 4:
When dividing 52 by 7, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 887.0
Deduct 49 from 52 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 7

Step 5:
The number 7 fits into 32 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 8874.0
Deduct 28 from 32 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 7

On to step 6:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 88745.0
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.

On to step 7:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 88745.7
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.

On to step 8:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 88745.71
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.

Going ahead to step 9:
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: 88745.714
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.

Advancing to step 10:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 88745.7142
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.

Step 11:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 88745.71428
If we take 56 away from 60, we end up 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.

Step 12:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 88745.714285
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.

On to step 13:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 88745.7142857
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.

Step 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 88745.71428571
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.

The final result is 88745.71428571 with a remainder of 3e-09.
