We divide 43719321 by 20
We're looking to find how many times 20 goes into 43719321.

Going ahead to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 20

Let's proceed to step 2:
If we divide 43 by 20, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 43 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 20

Going ahead to step 3:
If we divide 37 by 20, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 20 away from 37, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 20

Advancing to step 4:
The number 20 fits into 171 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 218.0
Subtracting 160 from 171 leaves us with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 20

Advancing to step 5:
119 divided by 20 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 2185.0
Deduct 100 from 119 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 20

Moving on to step 6:
20 goes into 193 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 21859.0
Deduct 180 from 193 and we're left with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 20

Moving on to step 7:
20 goes into 132 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 218596.0
The remainder is 12 after subtracting 120 from 132.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 20

Step 8:
The number 20 fits into 121 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 2185966.0
Subtracting 120 from 121 leaves us with 1.
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 9:
20 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2185966.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2185966.05
If we take 100 away from 100, 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.

Going ahead to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2185966.05
Subtract 0 from 0 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.

On to step 12:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2185966.05
Subtract 0 from 0 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.

Our division results in 2185966.05 with a remaining 0.0.
