We look at the division of 21404621 by 179 
Our goal is to divide 21404621 by 179.

Moving on to step 1:
2 divided by 179 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 179

Let's proceed to step 2:
If we divide 21 by 179, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 179

On to step 3:
179 goes into 214 1 times with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 179 from 214, we get 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 179

On to step 4:
350 divided by 179 is 1 with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 179 away from 350, we end up with 171.
Take the next digit (4) from the dividend and append it to 171, then repeat: 1714 / 179

On to step 5:
179 can be fit into 1714 9 times, resulting in a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we take 1611 away from 1714, we end up with 103.
Bring next digit (6) of the dividend behind the 103 and repeat the process: 1036 / 179

Step 6:
179 can be fit into 1036 5 times, resulting in a remainder of 141.
The number 5 becomes the next digit in our result. 
Result so far: 1195.0
Subtract 895 from 1036 to get 141.
Fetch the next digit (2) from the dividend, attach it to 141 and continue: 1412 / 179

On to step 7:
The number 179 fits into 1412 7 times, leaving a remainder of 159.
The number 7 becomes the next digit in our result. 
Result so far: 11957.0
Subtract 1253 from 1412 to get 159.
Grab the next digit (1) from the dividend, add it to 159, then carry on: 1591 / 179

Going ahead to step 8:
When dividing 1591 by 179, we get 8 with a remainder of 159.
The number 8 becomes the next digit in our result. 
Result so far: 119578.0
Subtracting 1432 from 1591 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
If we divide 1590 by 179, we get 8 and a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 119578.8
The remainder is 158 after subtracting 1432 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 10:
1580 divided by 179 is 8 with a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 119578.88
Subtracting 1432 from 1580 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 119578.88, with a leftover of 0.148.
