We're dividing 269691 by 51 
We're looking to find how many times 51 goes into 269691.

Step 1:
51 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 51

Going ahead to step 2:
51 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 51

Advancing to step 3:
The number 51 fits into 269 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 255 from 269 leaves us with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 51

Advancing to step 4:
The number 51 fits into 146 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 102 away from 146, we end up with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 51

Advancing to step 5:
When dividing 449 by 51, we get 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 528.0
Deduct 408 from 449 and we're left with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 51

Let's proceed to step 6:
The number 51 fits into 411 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 5288.0
Subtracting 408 from 411 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 51, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5288.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
51 goes into 300 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5288.05
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
When dividing 450 by 51, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 5288.058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 5288.0588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 5288.0588, and the remainder is 0.00012.
