51029398 ÷ 240 
We want to figure out the number of times 51029398 can be divided by 240.

Moving on to step 1:
If we divide 5 by 240, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 240

On to step 2:
51 divided by 240 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 240

Step 3:
240 can be fit into 510 2 times, resulting in a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 480 from 510 leaves us with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 240

Step 4:
240 goes into 302 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 240 from 302, we get 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 240

Moving on to step 5:
629 divided by 240 is 2 with a remainder of 149.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we subtract 480 from 629, we get 149.
Append the next digit (3) from the dividend to 149 and continue with: 1493 / 240

Advancing to step 6:
When dividing 1493 by 240, we get 6 with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 2126.0
If we take 1440 away from 1493, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 240

On to step 7:
When dividing 539 by 240, we get 2 with a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 21262.0
Subtract 480 from 539 to get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 240

On to step 8:
240 goes into 598 2 times with a remainder of 118.
The next digit of our result is 2. 
Result so far: 212622.0
The remainder is 118 after subtracting 480 from 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
1180 divided by 240 is 4 with a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 212622.4
If we take 960 away from 1180, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
When dividing 2200 by 240, we get 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 212622.49
If we take 2160 away from 2200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 240 is 1 with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 212622.491
If we subtract 240 from 400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
The number 240 fits into 1600 6 times, leaving a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 212622.4916
The remainder is 160 after subtracting 1440 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
1600 divided by 240 is 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 212622.49166
If we subtract 1440 from 1600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 212622.49166 with a balance of 0.00016.
