We're dividing 721198 by 10 
We want to divide 721198 by 10.

Step 1:
The number 10 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 10

On to step 2:
If we divide 72 by 10, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 70 from 72, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Let's proceed to step 3:
The number 10 fits into 21 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 20 from 21 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 10

Advancing to step 4:
If we divide 11 by 10, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 721.0
Deduct 10 from 11 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 10

Moving on to step 5:
10 goes into 19 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 7211.0
Deduct 10 from 19 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 10

Let's proceed to step 6:
10 can be fit into 98 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 72119.0
If we subtract 90 from 98, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
10 goes into 80 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 72119.8
Subtract 80 from 80 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.

Moving on to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 72119.8
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 72119.8
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 72119.8, and the remainder is 0.0.
