We look at the division of 421099 by 7 
Our goal is to divide 421099 by 7.

Let's proceed to step 1:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 7

Let's proceed to step 2:
The number 7 fits into 42 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 42 from 42 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 7

Advancing to step 3:
When dividing 1 by 7, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 7

Let's proceed to step 4:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 601.0
Subtract 7 from 10 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 7

Moving on to step 5:
The number 7 fits into 39 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 6015.0
The remainder is 4 after subtracting 35 from 39.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 7

On to step 6:
7 can be fit into 49 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 60157.0
Subtract 49 from 49 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
7 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60157.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 7 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 60157.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 60157.0, and the remainder is 0.0.
