87104748 ÷ 997 
The aim is to understand the frequency of 997 in 87104748.

Going ahead to step 1:
997 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 997

Let's proceed to step 2:
The number 997 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 997

Let's proceed to step 3:
If we divide 871 by 997, we get 0 and a remainder of 871.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 871 to get 871.
Bring next digit (0) of the dividend behind the 871 and repeat the process: 8710 / 997

Moving on to step 4:
8710 divided by 997 is 8 with a remainder of 734.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 734 after subtracting 7976 from 8710.
Append the next digit (4) from the dividend to 734 and continue with: 7344 / 997

On to step 5:
997 can be fit into 7344 7 times, resulting in a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 6979 away from 7344, we end up with 365.
Bring next digit (7) of the dividend behind the 365 and repeat the process: 3657 / 997

On to step 6:
3657 divided by 997 is 3 with a remainder of 666.
Record the quotient 3 as the next digit in the result. 
Result so far: 873.0
If we subtract 2991 from 3657, we get 666.
Take the next digit (4) from the dividend and append it to 666, then repeat: 6664 / 997

Advancing to step 7:
If we divide 6664 by 997, we get 6 and a remainder of 682.
Use 6 as the next digit of our solution. 
Result so far: 8736.0
Subtracting 5982 from 6664 leaves us with 682.
Bring next digit (8) of the dividend behind the 682 and repeat the process: 6828 / 997

Going ahead to step 8:
6828 divided by 997 is 6 with a remainder of 846.
The number 6 becomes the next digit in our result. 
Result so far: 87366.0
Deduct 5982 from 6828 and we're left with 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Let's proceed to step 9:
997 goes into 8460 8 times with a remainder of 484.
Use 8 as the next digit of our solution. 
Result so far: 87366.8
If we take 7976 away from 8460, 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.

Moving on to step 10:
997 can be fit into 4840 4 times, resulting in a remainder of 852.
The next digit of our result is 4. 
Result so far: 87366.84
If we take 3988 away from 4840, we end up with 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

On to step 11:
If we divide 8520 by 997, we get 8 and a remainder of 544.
The number 8 becomes the next digit in our result. 
Result so far: 87366.848
Subtract 7976 from 8520 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 12:
5440 divided by 997 is 5 with a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 87366.8485
Subtract 4985 from 5440 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 13:
4550 divided by 997 is 4 with a remainder of 562.
Record the quotient 4 as the next digit in the result. 
Result so far: 87366.84854
Subtract 3988 from 4550 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 14:
5620 divided by 997 is 5 with a remainder of 635.
Write down 5 as next digit of the result. 
Result so far: 87366.848545
Deduct 4985 from 5620 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 15:
If we divide 6350 by 997, we get 6 and a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 87366.8485456
Subtracting 5982 from 6350 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 16:
If we divide 3680 by 997, we get 3 and a remainder of 689.
Write down 3 as next digit of the result. 
Result so far: 87366.84854563
Deduct 2991 from 3680 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

The final outcome is 87366.84854563, with a leftover of 6.89e-07.
