We're dividing 98251921 by 877 
The aim is to understand the frequency of 877 in 98251921.

Step 1:
877 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 877

Advancing to step 2:
98 divided by 877 is 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Append the next digit (2) from the dividend to 98 and continue with: 982 / 877

Advancing to step 3:
982 divided by 877 is 1 with a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 877 away from 982, we end up with 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 877

Let's proceed to step 4:
If we divide 1055 by 877, we get 1 and a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 877 from 1055 to get 178.
Bring next digit (1) of the dividend behind the 178 and repeat the process: 1781 / 877

Let's proceed to step 5:
877 can be fit into 1781 2 times, resulting in a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 1754 away from 1781, we end up with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 877

Step 6:
The number 877 fits into 279 0 times, leaving a remainder of 279.
Write down 0 as next digit of the result. 
Result so far: 1120.0
Subtract 0 from 279 to get 279.
Take the next digit (2) from the dividend and append it to 279, then repeat: 2792 / 877

Going ahead to step 7:
If we divide 2792 by 877, we get 3 and a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 11203.0
If we subtract 2631 from 2792, we get 161.
Grab the next digit (1) from the dividend, add it to 161, then carry on: 1611 / 877

Step 8:
The number 877 fits into 1611 1 times, leaving a remainder of 734.
The number 1 becomes the next digit in our result. 
Result so far: 112031.0
If we take 877 away from 1611, we end up with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Step 9:
877 can be fit into 7340 8 times, resulting in a remainder of 324.
Write down 8 as next digit of the result. 
Result so far: 112031.8
Deduct 7016 from 7340 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 10:
877 can be fit into 3240 3 times, resulting in a remainder of 609.
Use 3 as the next digit of our solution. 
Result so far: 112031.83
If we take 2631 away from 3240, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Step 11:
877 goes into 6090 6 times with a remainder of 828.
Use 6 as the next digit of our solution. 
Result so far: 112031.836
Subtract 5262 from 6090 to get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

On to step 12:
877 can be fit into 8280 9 times, resulting in a remainder of 387.
The number 9 becomes the next digit in our result. 
Result so far: 112031.8369
The remainder is 387 after subtracting 7893 from 8280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 13:
877 can be fit into 3870 4 times, resulting in a remainder of 362.
The next digit of our result is 4. 
Result so far: 112031.83694
If we take 3508 away from 3870, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 14:
3620 divided by 877 is 4 with a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 112031.836944
Subtract 3508 from 3620 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 112031.836944 and a remainder of 1.12e-05.
