25428876 ÷ 902 
We want to figure out the number of times 25428876 can be divided by 902.

Step 1:
902 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 902

Step 2:
25 divided by 902 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.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 902

On to step 3:
254 divided by 902 is 0 with a remainder of 254.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 254, we get 254.
Fetch the next digit (2) from the dividend, attach it to 254 and continue: 2542 / 902

Going ahead to step 4:
902 goes into 2542 2 times with a remainder of 738.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 738 after subtracting 1804 from 2542.
Include the next digit (8) from the dividend after 738, then repeat: 7388 / 902

On to step 5:
If we divide 7388 by 902, we get 8 and a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 7216 from 7388 and we're left with 172.
Include the next digit (8) from the dividend after 172, then repeat: 1728 / 902

Advancing to step 6:
902 goes into 1728 1 times with a remainder of 826.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 902 from 1728 to get 826.
Append the next digit (7) from the dividend to 826 and continue with: 8267 / 902

Going ahead to step 7:
If we divide 8267 by 902, we get 9 and a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 2819.0
Subtract 8118 from 8267 to get 149.
Fetch the next digit (6) from the dividend, attach it to 149 and continue: 1496 / 902

Let's proceed to step 8:
902 can be fit into 1496 1 times, resulting in a remainder of 594.
Write down 1 as next digit of the result. 
Result so far: 28191.0
Deduct 902 from 1496 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 9:
If we divide 5940 by 902, we get 6 and a remainder of 528.
The next digit of our result is 6. 
Result so far: 28191.6
Deduct 5412 from 5940 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 10:
When dividing 5280 by 902, we get 5 with a remainder of 770.
Put 5 as the next digit of the answer. 
Result so far: 28191.65
Subtract 4510 from 5280 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 11:
If we divide 7700 by 902, we get 8 and a remainder of 484.
Write down 8 as next digit of the result. 
Result so far: 28191.658
If we take 7216 away from 7700, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 12:
4840 divided by 902 is 5 with a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 28191.6585
Subtract 4510 from 4840 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 13:
If we divide 3300 by 902, we get 3 and a remainder of 594.
The next digit of our result is 3. 
Result so far: 28191.65853
The remainder is 594 after subtracting 2706 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 14:
5940 divided by 902 is 6 with a remainder of 528.
Write down 6 as next digit of the result. 
Result so far: 28191.658536
Deduct 5412 from 5940 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 15:
When dividing 5280 by 902, we get 5 with a remainder of 770.
Put 5 as the next digit of the answer. 
Result so far: 28191.6585365
Subtract 4510 from 5280 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 16:
7700 divided by 902 is 8 with a remainder of 484.
The next digit of our result is 8. 
Result so far: 28191.65853658
Deduct 7216 from 7700 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final outcome is 28191.65853658, with a leftover of 4.84e-07.
