87169663 divided by 715 
The aim is to understand the frequency of 715 in 87169663.

Advancing to step 1:
When dividing 8 by 715, we get 0 with 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.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 715

Step 2:
715 goes into 87 0 times with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 715

Step 3:
715 goes into 871 1 times with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 156 after subtracting 715 from 871.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 715

Advancing to step 4:
The number 715 fits into 1566 2 times, leaving a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1430 from 1566 and we're left with 136.
Append the next digit (9) from the dividend to 136 and continue with: 1369 / 715

Advancing to step 5:
715 goes into 1369 1 times with a remainder of 654.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 715 from 1369 and we're left with 654.
Bring next digit (6) of the dividend behind the 654 and repeat the process: 6546 / 715

Moving on to step 6:
715 can be fit into 6546 9 times, resulting in a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 1219.0
If we subtract 6435 from 6546, we get 111.
Include the next digit (6) from the dividend after 111, then repeat: 1116 / 715

Advancing to step 7:
1116 divided by 715 is 1 with a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 12191.0
If we subtract 715 from 1116, we get 401.
Bring next digit (3) of the dividend behind the 401 and repeat the process: 4013 / 715

Let's proceed to step 8:
4013 divided by 715 is 5 with a remainder of 438.
Put 5 as the next digit of the answer. 
Result so far: 121915.0
Subtracting 3575 from 4013 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 9:
The number 715 fits into 4380 6 times, leaving a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 121915.6
Deduct 4290 from 4380 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
When dividing 900 by 715, we get 1 with a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 121915.61
Subtracting 715 from 900 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 11:
When dividing 1850 by 715, we get 2 with a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 121915.612
If we take 1430 away from 1850, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
The number 715 fits into 4200 5 times, leaving a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 121915.6125
If we take 3575 away from 4200, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 13:
6250 divided by 715 is 8 with a remainder of 530.
Put 8 as the next digit of the answer. 
Result so far: 121915.61258
If we subtract 5720 from 6250, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
The number 715 fits into 5300 7 times, leaving a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 121915.612587
Subtract 5005 from 5300 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 15:
715 goes into 2950 4 times with a remainder of 90.
The next digit of our result is 4. 
Result so far: 121915.6125874
Subtract 2860 from 2950 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 16:
When dividing 900 by 715, we get 1 with a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 121915.61258741
Deduct 715 from 900 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

After the division, we end up with 121915.61258741 and a remainder of 1.85e-07.
