Let's divide 25510928 by 901
The aim is to understand the frequency of 901 in 25510928.

Let's proceed to step 1:
The number 901 fits into 2 0 times, leaving 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.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 901

Step 2:
When dividing 25 by 901, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 901

Step 3:
The number 901 fits into 255 0 times, leaving a remainder of 255.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 255, we end up with 255.
Fetch the next digit (1) from the dividend, attach it to 255 and continue: 2551 / 901

Moving on to step 4:
The number 901 fits into 2551 2 times, leaving a remainder of 749.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1802 from 2551 and we're left with 749.
Take the next digit (0) from the dividend and append it to 749, then repeat: 7490 / 901

Step 5:
901 goes into 7490 8 times with a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 7208 away from 7490, we end up with 282.
Fetch the next digit (9) from the dividend, attach it to 282 and continue: 2829 / 901

Advancing to step 6:
901 can be fit into 2829 3 times, resulting in a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 283.0
Subtracting 2703 from 2829 leaves us with 126.
Fetch the next digit (2) from the dividend, attach it to 126 and continue: 1262 / 901

On to step 7:
The number 901 fits into 1262 1 times, leaving a remainder of 361.
Write down 1 as next digit of the result. 
Result so far: 2831.0
Deduct 901 from 1262 and we're left with 361.
Fetch the next digit (8) from the dividend, attach it to 361 and continue: 3618 / 901

Step 8:
901 can be fit into 3618 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 28314.0
If we subtract 3604 from 3618, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 901 fits into 140 0 times, leaving a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 28314.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
901 can be fit into 1400 1 times, resulting in a remainder of 499.
Put 1 as the next digit of the answer. 
Result so far: 28314.01
Subtracting 901 from 1400 leaves us with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 11:
901 goes into 4990 5 times with a remainder of 485.
The next digit of our result is 5. 
Result so far: 28314.015
The remainder is 485 after subtracting 4505 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 12:
If we divide 4850 by 901, we get 5 and a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 28314.0155
If we take 4505 away from 4850, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 28314.0155, with a leftover of 0.00345.
