123451 ÷ 69 
Our goal is to divide 123451 by 69.

Moving on to step 1:
69 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 69

Let's proceed to step 2:
The number 69 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 69

Let's proceed to step 3:
123 divided by 69 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 69 away from 123, we end up with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 69

Moving on to step 4:
69 goes into 544 7 times with a remainder of 61.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 483 from 544 and we're left with 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 69

Moving on to step 5:
69 can be fit into 615 8 times, resulting in a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 178.0
If we subtract 552 from 615, we get 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 69

Going ahead to step 6:
69 can be fit into 631 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 1789.0
Deduct 621 from 631 and we're left 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.

Step 7:
69 can be fit into 100 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1789.1
Deduct 69 from 100 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
69 goes into 310 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1789.14
Deduct 276 from 310 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
If we divide 340 by 69, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 1789.144
Subtract 276 from 340 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 1789.144, with a leftover of 0.0064.
