51297299 ÷ 69 
We want to divide 51297299 by 69.

Let's proceed to step 1:
If we divide 5 by 69, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 69

Step 2:
When dividing 51 by 69, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 69

Advancing to step 3:
When dividing 512 by 69, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 483 away from 512, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 69

Advancing to step 4:
299 divided by 69 is 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 276 from 299 to get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 69

Let's proceed to step 5:
If we divide 237 by 69, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 743.0
If we take 207 away from 237, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 69

On to step 6:
69 goes into 302 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7434.0
The remainder is 26 after subtracting 276 from 302.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 69

Moving on to step 7:
When dividing 269 by 69, we get 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 74343.0
If we subtract 207 from 269, we get 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 69

Let's proceed to step 8:
69 can be fit into 629 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 743439.0
Deduct 621 from 629 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
69 goes into 80 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 743439.1
Deduct 69 from 80 and we're left 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.

Let's proceed to step 10:
When dividing 110 by 69, we get 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 743439.11
If we take 69 away from 110, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 743439.11 and a remainder of 0.041.
