We divide 372571 by 20
We want to figure out the number of times 372571 can be divided by 20.

Let's proceed to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 20

Let's proceed to step 2:
When dividing 37 by 20, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 20 from 37, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 20

Moving on to step 3:
When dividing 172 by 20, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 160 from 172 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 20

On to step 4:
If we divide 125 by 20, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we subtract 120 from 125, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Going ahead to step 5:
If we divide 57 by 20, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 1862.0
The remainder is 17 after subtracting 40 from 57.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 20

Let's proceed to step 6:
20 can be fit into 171 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 18628.0
Subtract 160 from 171 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 18628.5
Deduct 100 from 110 and we're left 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 18628.55
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.

The final outcome is 18628.55, with a leftover of 0.0.
