We look at the division of 20129359 by 269 
We want to figure out the number of times 20129359 can be divided by 269.

Step 1:
The number 269 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 269

Advancing to step 2:
The number 269 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 269

On to step 3:
269 can be fit into 201 0 times, resulting in a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 201 and we're left with 201.
Append the next digit (2) from the dividend to 201 and continue with: 2012 / 269

On to step 4:
When dividing 2012 by 269, we get 7 with a remainder of 129.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 1883 from 2012 to get 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 269

Moving on to step 5:
The number 269 fits into 1299 4 times, leaving a remainder of 223.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 1076 away from 1299, we end up with 223.
Append the next digit (3) from the dividend to 223 and continue with: 2233 / 269

Advancing to step 6:
The number 269 fits into 2233 8 times, leaving a remainder of 81.
Use 8 as the next digit of our solution. 
Result so far: 748.0
The remainder is 81 after subtracting 2152 from 2233.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 269

On to step 7:
269 can be fit into 815 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 7483.0
Subtracting 807 from 815 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 269

Advancing to step 8:
The number 269 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 74830.0
If we subtract 0 from 89, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
The number 269 fits into 890 3 times, leaving a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 74830.3
Deduct 807 from 890 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 10:
269 can be fit into 830 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 74830.33
If we subtract 807 from 830, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 74830.33, with a leftover of 0.023.
