We divide 150951 by 20
Our goal is to divide 150951 by 20.

Step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

On to step 2:
20 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 20

Going ahead to step 3:
The number 20 fits into 150 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 10 after subtracting 140 from 150.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 20

Going ahead to step 4:
If we divide 109 by 20, we get 5 and a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 100 from 109 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 20

Moving on to step 5:
20 can be fit into 95 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 754.0
If we take 80 away from 95, we end up with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 20

Going ahead to step 6:
The number 20 fits into 151 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7547.0
If we take 140 away from 151, we end up with 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:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7547.5
If we take 100 away from 110, 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.

On to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7547.55
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 quotient of the division is 7547.55, and the remainder is 0.0.
