Let's divide 153707 by 20
We want to figure out the number of times 153707 can be divided by 20.

Going ahead to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

On to step 2:
When dividing 15 by 20, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 20

Going ahead to step 3:
153 divided by 20 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 140 from 153 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 20

Going ahead to step 4:
If we divide 137 by 20, we get 6 and a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 120 from 137 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 20

Going ahead to step 5:
If we divide 170 by 20, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 768.0
Subtract 160 from 170 to get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 20

Let's proceed to step 6:
20 goes into 107 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 7685.0
Deduct 100 from 107 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 20, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 7685.3
Subtract 60 from 70 to 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.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7685.35
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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7685.35
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7685.35
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.

The final result is 7685.35 with a remainder of 0.0.
