25642040 ÷ 751 
We want to figure out the number of times 25642040 can be divided by 751.

Going ahead to step 1:
2 divided by 751 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 751

Advancing to step 2:
25 divided by 751 is 0 with 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.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 751

Going ahead to step 3:
751 can be fit into 256 0 times, resulting in a remainder of 256.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 256 and we're left with 256.
Append the next digit (4) from the dividend to 256 and continue with: 2564 / 751

Step 4:
When dividing 2564 by 751, we get 3 with a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2253 from 2564 and we're left with 311.
Append the next digit (2) from the dividend to 311 and continue with: 3112 / 751

On to step 5:
The number 751 fits into 3112 4 times, leaving a remainder of 108.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 3004 from 3112 leaves us with 108.
Bring next digit (0) of the dividend behind the 108 and repeat the process: 1080 / 751

On to step 6:
If we divide 1080 by 751, we get 1 and a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 341.0
Subtracting 751 from 1080 leaves us with 329.
Bring next digit (4) of the dividend behind the 329 and repeat the process: 3294 / 751

Going ahead to step 7:
The number 751 fits into 3294 4 times, leaving a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 3414.0
The remainder is 290 after subtracting 3004 from 3294.
Include the next digit (0) from the dividend after 290, then repeat: 2900 / 751

Advancing to step 8:
If we divide 2900 by 751, we get 3 and a remainder of 647.
Record the quotient 3 as the next digit in the result. 
Result so far: 34143.0
If we take 2253 away from 2900, we end up with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Advancing to step 9:
The number 751 fits into 6470 8 times, leaving a remainder of 462.
The number 8 becomes the next digit in our result. 
Result so far: 34143.8
Deduct 6008 from 6470 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 10:
751 can be fit into 4620 6 times, resulting in a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 34143.86
Subtracting 4506 from 4620 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 11:
751 goes into 1140 1 times with a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 34143.861
Subtract 751 from 1140 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 12:
The number 751 fits into 3890 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 34143.8615
If we subtract 3755 from 3890, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 13:
751 goes into 1350 1 times with a remainder of 599.
The number 1 becomes the next digit in our result. 
Result so far: 34143.86151
If we subtract 751 from 1350, we get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Advancing to step 14:
The number 751 fits into 5990 7 times, leaving a remainder of 733.
Record the quotient 7 as the next digit in the result. 
Result so far: 34143.861517
The remainder is 733 after subtracting 5257 from 5990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Step 15:
7330 divided by 751 is 9 with a remainder of 571.
The next digit of our result is 9. 
Result so far: 34143.8615179
Subtract 6759 from 7330 to get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 16:
If we divide 5710 by 751, we get 7 and a remainder of 453.
Use 7 as the next digit of our solution. 
Result so far: 34143.86151797
If we take 5257 away from 5710, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

The final outcome is 34143.86151797, with a leftover of 4.53e-07.
