61757921 ÷ 25 
We want to figure out the number of times 61757921 can be divided by 25.

On to step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 25

Advancing to step 2:
When dividing 61 by 25, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 50 from 61, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 25

Going ahead to step 3:
117 divided by 25 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 100 from 117 and we're left with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 25

On to step 4:
25 goes into 175 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 247.0
Deduct 175 from 175 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 25

Advancing to step 5:
7 divided by 25 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 2470.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 25

Step 6:
The number 25 fits into 79 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 24703.0
If we take 75 away from 79, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 25

Moving on to step 7:
25 can be fit into 42 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 247031.0
Deduct 25 from 42 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 25

Going ahead to step 8:
25 can be fit into 171 6 times, resulting in a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 2470316.0
If we subtract 150 from 171, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 25, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 2470316.8
The remainder is 10 after subtracting 200 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2470316.84
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2470316.84
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2470316.84
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2470316.84, and the remainder is 0.0.
