87069851 divided by 715 
The aim is to understand the frequency of 715 in 87069851.

Let's proceed to step 1:
8 divided by 715 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 715

Let's proceed to step 2:
87 divided by 715 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 715

Let's proceed to step 3:
If we divide 870 by 715, we get 1 and a remainder of 155.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 155 after subtracting 715 from 870.
Include the next digit (6) from the dividend after 155, then repeat: 1556 / 715

Let's proceed to step 4:
715 can be fit into 1556 2 times, resulting in a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 126 after subtracting 1430 from 1556.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 715

Step 5:
1269 divided by 715 is 1 with a remainder of 554.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 715 from 1269 to get 554.
Append the next digit (8) from the dividend to 554 and continue with: 5548 / 715

Advancing to step 6:
When dividing 5548 by 715, we get 7 with a remainder of 543.
Put 7 as the next digit of the answer. 
Result so far: 1217.0
Subtract 5005 from 5548 to get 543.
Append the next digit (5) from the dividend to 543 and continue with: 5435 / 715

Going ahead to step 7:
If we divide 5435 by 715, we get 7 and a remainder of 430.
Record the quotient 7 as the next digit in the result. 
Result so far: 12177.0
The remainder is 430 after subtracting 5005 from 5435.
Include the next digit (1) from the dividend after 430, then repeat: 4301 / 715

Advancing to step 8:
4301 divided by 715 is 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 121776.0
Subtracting 4290 from 4301 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
715 goes into 110 0 times with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 121776.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
715 can be fit into 1100 1 times, resulting in a remainder of 385.
Put 1 as the next digit of the answer. 
Result so far: 121776.01
Deduct 715 from 1100 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 11:
3850 divided by 715 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 121776.015
If we take 3575 away from 3850, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 12:
The number 715 fits into 2750 3 times, leaving a remainder of 605.
Record the quotient 3 as the next digit in the result. 
Result so far: 121776.0153
If we subtract 2145 from 2750, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 13:
When dividing 6050 by 715, we get 8 with a remainder of 330.
The next digit of our result is 8. 
Result so far: 121776.01538
If we subtract 5720 from 6050, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 14:
When dividing 3300 by 715, we get 4 with a remainder of 440.
Put 4 as the next digit of the answer. 
Result so far: 121776.015384
The remainder is 440 after subtracting 2860 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 15:
715 can be fit into 4400 6 times, resulting in a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 121776.0153846
Subtracting 4290 from 4400 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
715 goes into 1100 1 times with a remainder of 385.
Put 1 as the next digit of the answer. 
Result so far: 121776.01538461
If we take 715 away from 1100, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

After the division, we end up with 121776.01538461 and a remainder of 3.85e-07.
