We're dividing 371657 by 20 
We're looking to find how many times 20 goes into 371657.

Let's proceed to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 20

Moving on to step 2:
37 divided by 20 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 20 away from 37, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 20

On to step 3:
20 can be fit into 171 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 160 from 171 and we're left with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 20

Advancing to step 4:
When dividing 116 by 20, we get 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtracting 100 from 116 leaves us with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 20

Let's proceed to step 5:
165 divided by 20 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 1858.0
Deduct 160 from 165 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Advancing to step 6:
20 can be fit into 57 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 18582.0
The remainder is 17 after subtracting 40 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
When dividing 170 by 20, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 18582.8
If we subtract 160 from 170, 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.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 18582.85
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 next digit of our result is 0. 
Result so far: 18582.85
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.

Advancing to step 10:
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: 18582.85
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.

After the division, we end up with 18582.85 and a remainder of 0.0.
