We're dividing 87260942 by 977 
The aim is to understand the frequency of 977 in 87260942.

Step 1:
The number 977 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 977

Let's proceed to step 2:
If we divide 87 by 977, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 977

Moving on to step 3:
977 can be fit into 872 0 times, resulting in a remainder of 872.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 872 after subtracting 0 from 872.
Grab the next digit (6) from the dividend, add it to 872, then carry on: 8726 / 977

Let's proceed to step 4:
When dividing 8726 by 977, we get 8 with a remainder of 910.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7816 from 8726, we get 910.
Take the next digit (0) from the dividend and append it to 910, then repeat: 9100 / 977

Advancing to step 5:
When dividing 9100 by 977, we get 9 with a remainder of 307.
The next digit of our result is 9. 
Result so far: 89.0
If we take 8793 away from 9100, we end up with 307.
Grab the next digit (9) from the dividend, add it to 307, then carry on: 3079 / 977

On to step 6:
The number 977 fits into 3079 3 times, leaving a remainder of 148.
The next digit of our result is 3. 
Result so far: 893.0
If we take 2931 away from 3079, we end up with 148.
Grab the next digit (4) from the dividend, add it to 148, then carry on: 1484 / 977

Moving on to step 7:
977 can be fit into 1484 1 times, resulting in a remainder of 507.
Use 1 as the next digit of our solution. 
Result so far: 8931.0
If we take 977 away from 1484, we end up with 507.
Take the next digit (2) from the dividend and append it to 507, then repeat: 5072 / 977

Step 8:
When dividing 5072 by 977, we get 5 with a remainder of 187.
The next digit of our result is 5. 
Result so far: 89315.0
If we subtract 4885 from 5072, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 9:
977 goes into 1870 1 times with a remainder of 893.
Put 1 as the next digit of the answer. 
Result so far: 89315.1
The remainder is 893 after subtracting 977 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8930, and continue the process.

Going ahead to step 10:
When dividing 8930 by 977, we get 9 with a remainder of 137.
Use 9 as the next digit of our solution. 
Result so far: 89315.19
The remainder is 137 after subtracting 8793 from 8930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 11:
977 goes into 1370 1 times with a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 89315.191
Deduct 977 from 1370 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 12:
If we divide 3930 by 977, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 89315.1914
The remainder is 22 after subtracting 3908 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
977 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 89315.1914
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
When dividing 2200 by 977, we get 2 with a remainder of 246.
Use 2 as the next digit of our solution. 
Result so far: 89315.191402
The remainder is 246 after subtracting 1954 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 15:
The number 977 fits into 2460 2 times, leaving a remainder of 506.
Record the quotient 2 as the next digit in the result. 
Result so far: 89315.1914022
If we subtract 1954 from 2460, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The final outcome is 89315.1914022, with a leftover of 5.06e-06.
