25555770 ÷ 97 
We want to figure out the number of times 25555770 can be divided by 97.

Step 1:
When dividing 2 by 97, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 97

Step 2:
The number 97 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 97

Going ahead to step 3:
255 divided by 97 is 2 with a remainder of 61.
The next digit of our result is 2. 
Result so far: 2.0
If we take 194 away from 255, we end up with 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 97

Moving on to step 4:
97 goes into 615 6 times with a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 582 from 615 leaves us with 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 97

Step 5:
335 divided by 97 is 3 with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 263.0
If we subtract 291 from 335, we get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 97

Moving on to step 6:
447 divided by 97 is 4 with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 2634.0
If we take 388 away from 447, we end up with 59.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 97

Moving on to step 7:
97 can be fit into 597 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 26346.0
Deduct 582 from 597 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 97

On to step 8:
The number 97 fits into 150 1 times, leaving a remainder of 53.
The next digit of our result is 1. 
Result so far: 263461.0
If we subtract 97 from 150, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
If we divide 530 by 97, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 263461.5
The remainder is 45 after subtracting 485 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
If we divide 450 by 97, we get 4 and a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 263461.54
If we subtract 388 from 450, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
97 goes into 620 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 263461.546
If we take 582 away from 620, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
The number 97 fits into 380 3 times, leaving a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 263461.5463
Subtract 291 from 380 to 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.

Step 13:
890 divided by 97 is 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 263461.54639
Subtract 873 from 890 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
If we divide 170 by 97, we get 1 and a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 263461.546391
Deduct 97 from 170 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 15:
730 divided by 97 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 263461.5463917
If we take 679 away from 730, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 16:
97 can be fit into 510 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 263461.54639175
Deduct 485 from 510 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 263461.54639175 with a remainder of 2.5e-08.
