We look at the division of 69143654 by 20 
We want to divide 69143654 by 20.

Moving on to step 1:
20 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 20

Step 2:
20 can be fit into 69 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 60 from 69, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 20

Let's proceed to step 3:
The number 20 fits into 91 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 80 away from 91, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 20

Moving on to step 4:
When dividing 114 by 20, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
Subtracting 100 from 114 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 20

On to step 5:
If we divide 143 by 20, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 3457.0
If we take 140 away from 143, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 20

Moving on to step 6:
The number 20 fits into 36 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 34571.0
Deduct 20 from 36 and we're left with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 20

Advancing to step 7:
20 can be fit into 165 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 345718.0
Deduct 160 from 165 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 20

Step 8:
20 can be fit into 54 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 3457182.0
Subtracting 40 from 54 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
140 divided by 20 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 3457182.7
The remainder is 0 after subtracting 140 from 140.
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3457182.7
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 11:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3457182.7
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 outcome is 3457182.7, with a leftover of 0.0.
