Let's divide 76497651 by 87
The aim is to understand the frequency of 87 in 76497651.

Going ahead to step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 87

Going ahead to step 2:
If we divide 76 by 87, we get 0 and a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 87

Step 3:
When dividing 764 by 87, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 68 after subtracting 696 from 764.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 87

Advancing to step 4:
689 divided by 87 is 7 with a remainder of 80.
The next digit of our result is 7. 
Result so far: 87.0
The remainder is 80 after subtracting 609 from 689.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 87

Moving on to step 5:
If we divide 807 by 87, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 879.0
Deduct 783 from 807 and we're left with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 87

Let's proceed to step 6:
87 goes into 246 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 8792.0
If we take 174 away from 246, we end up with 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 87

Let's proceed to step 7:
The number 87 fits into 725 8 times, leaving a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 87928.0
Subtract 696 from 725 to get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 87

Step 8:
87 goes into 291 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 879283.0
Subtract 261 from 291 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
87 can be fit into 300 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 879283.3
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 10:
87 goes into 390 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 879283.34
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 879283.344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 879283.344, with a leftover of 0.0072.
