743501 divided by 20 
We're looking to find how many times 20 goes into 743501.

Going ahead to step 1:
7 divided by 20 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 20

Going ahead to step 2:
74 divided by 20 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 60 from 74 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 20

Let's proceed to step 3:
143 divided by 20 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 3 after subtracting 140 from 143.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 20

Going ahead to step 4:
35 divided by 20 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 371.0
If we take 20 away from 35, we end up with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 20

Let's proceed to step 5:
20 can be fit into 150 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3717.0
The remainder is 10 after subtracting 140 from 150.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 20

Step 6:
20 can be fit into 101 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 37175.0
If we take 100 away from 101, we end up 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.

Step 7:
The number 20 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 37175.0
If we take 0 away from 10, we end up with 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 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 37175.05
If we subtract 100 from 100, we 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37175.05
If we subtract 0 from 0, we 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 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37175.05
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.

The final outcome is 37175.05, with a leftover of 0.0.
