Let's divide 89730974 by 877
The aim is to understand the frequency of 877 in 89730974.

Step 1:
The number 877 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 877

Moving on to step 2:
877 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 877

Step 3:
877 goes into 897 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 877 from 897 leaves us with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 877

Advancing to step 4:
The number 877 fits into 203 0 times, leaving a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 203 to get 203.
Include the next digit (0) from the dividend after 203, then repeat: 2030 / 877

Step 5:
The number 877 fits into 2030 2 times, leaving a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 1754 away from 2030, we end up with 276.
Append the next digit (9) from the dividend to 276 and continue with: 2769 / 877

Let's proceed to step 6:
If we divide 2769 by 877, we get 3 and a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 1023.0
If we take 2631 away from 2769, we end up with 138.
Include the next digit (7) from the dividend after 138, then repeat: 1387 / 877

Let's proceed to step 7:
877 can be fit into 1387 1 times, resulting in a remainder of 510.
Put 1 as the next digit of the answer. 
Result so far: 10231.0
Subtracting 877 from 1387 leaves us with 510.
Bring next digit (4) of the dividend behind the 510 and repeat the process: 5104 / 877

On to step 8:
The number 877 fits into 5104 5 times, leaving a remainder of 719.
The number 5 becomes the next digit in our result. 
Result so far: 102315.0
Deduct 4385 from 5104 and we're left with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

On to step 9:
The number 877 fits into 7190 8 times, leaving a remainder of 174.
Use 8 as the next digit of our solution. 
Result so far: 102315.8
Deduct 7016 from 7190 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 10:
1740 divided by 877 is 1 with a remainder of 863.
Record the quotient 1 as the next digit in the result. 
Result so far: 102315.81
Subtracting 877 from 1740 leaves us with 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Step 11:
8630 divided by 877 is 9 with a remainder of 737.
The next digit of our result is 9. 
Result so far: 102315.819
Subtract 7893 from 8630 to get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

On to step 12:
877 goes into 7370 8 times with a remainder of 354.
The next digit of our result is 8. 
Result so far: 102315.8198
If we take 7016 away from 7370, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 13:
3540 divided by 877 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 102315.81984
Subtracting 3508 from 3540 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
320 divided by 877 is 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 102315.81984
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
877 can be fit into 3200 3 times, resulting in a remainder of 569.
The next digit of our result is 3. 
Result so far: 102315.8198403
The remainder is 569 after subtracting 2631 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 16:
The number 877 fits into 5690 6 times, leaving a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 102315.81984036
Deduct 5262 from 5690 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final result is 102315.81984036 with a remainder of 4.28e-07.
