69821751 divided by 20 
We want to figure out the number of times 69821751 can be divided by 20.

Let's proceed to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 20

Moving on to step 2:
The number 20 fits into 69 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 60 from 69 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

Advancing to step 3:
20 can be fit into 98 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 80 from 98 leaves us with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 20

On to step 4:
182 divided by 20 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 349.0
Subtract 180 from 182 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 20

Moving on to step 5:
If we divide 21 by 20, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3491.0
If we take 20 away from 21, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

Let's proceed to step 6:
20 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 34910.0
Subtract 0 from 17 to get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

Advancing to step 7:
175 divided by 20 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 349108.0
Deduct 160 from 175 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 20

Moving on to step 8:
20 goes into 151 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 3491087.0
Subtracting 140 from 151 leaves us 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.

On to step 9:
20 can be fit into 110 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3491087.5
Subtracting 100 from 110 leaves us 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.

Going ahead to step 10:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3491087.55
Subtract 100 from 100 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.

The final result is 3491087.55 with a remainder of 0.0.
