Let's divide 157980 by 25
We want to divide 157980 by 25.

Advancing to step 1:
When dividing 1 by 25, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 25

Advancing to step 2:
If we divide 15 by 25, we get 0 and 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 / 25

Advancing to step 3:
25 goes into 157 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 150 from 157 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 25

On to step 4:
When dividing 79 by 25, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 63.0
Deduct 75 from 79 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 25

Step 5:
The number 25 fits into 48 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 631.0
Subtract 25 from 48 to get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 25

Going ahead to step 6:
25 goes into 230 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 6319.0
If we subtract 225 from 230, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 6319.2
Deduct 50 from 50 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.

Advancing to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6319.2
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.

Advancing to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6319.2
The remainder is 0 after subtracting 0 from 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 6319.2, and the remainder is 0.0.
