We divide 70022159 by 638
Our goal is to divide 70022159 by 638.

Advancing to step 1:
7 divided by 638 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 638

Going ahead to step 2:
638 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 638

On to step 3:
700 divided by 638 is 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 638 from 700 leaves us with 62.
Take the next digit (2) from the dividend and append it to 62, then repeat: 622 / 638

Moving on to step 4:
622 divided by 638 is 0 with a remainder of 622.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 622 leaves us with 622.
Fetch the next digit (2) from the dividend, attach it to 622 and continue: 6222 / 638

Step 5:
6222 divided by 638 is 9 with a remainder of 480.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we take 5742 away from 6222, we end up with 480.
Bring next digit (1) of the dividend behind the 480 and repeat the process: 4801 / 638

Let's proceed to step 6:
If we divide 4801 by 638, we get 7 and a remainder of 335.
The number 7 becomes the next digit in our result. 
Result so far: 1097.0
Subtracting 4466 from 4801 leaves us with 335.
Take the next digit (5) from the dividend and append it to 335, then repeat: 3355 / 638

Advancing to step 7:
If we divide 3355 by 638, we get 5 and a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 10975.0
If we take 3190 away from 3355, we end up with 165.
Include the next digit (9) from the dividend after 165, then repeat: 1659 / 638

Going ahead to step 8:
If we divide 1659 by 638, we get 2 and a remainder of 383.
The number 2 becomes the next digit in our result. 
Result so far: 109752.0
If we subtract 1276 from 1659, we get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 9:
If we divide 3830 by 638, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 109752.6
Subtracting 3828 from 3830 leaves us 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.

Going ahead to step 10:
When dividing 20 by 638, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 109752.6
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
638 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 109752.6
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 109752.6 and a remainder of 0.02.
