157158 divided by 20 
We want to divide 157158 by 20.

Let's proceed to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 20

On to step 2:
15 divided by 20 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 20

Let's proceed to step 3:
When dividing 157 by 20, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 140 from 157 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 20

Step 4:
The number 20 fits into 171 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 160 from 171 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Going ahead to step 5:
20 can be fit into 115 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 785.0
Subtract 100 from 115 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 20

Advancing to step 6:
The number 20 fits into 158 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 7857.0
If we subtract 140 from 158, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
20 goes into 180 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 7857.9
Subtract 180 from 180 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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7857.9
If we take 0 away from 0, 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7857.9
Subtracting 0 from 0 leaves us 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.

Our division results in 7857.9 with a remaining 0.0.
