81858777 ÷ 715 
The aim is to understand the frequency of 715 in 81858777.

On to step 1:
715 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 715

Let's proceed to step 2:
The number 715 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 715

Going ahead to step 3:
715 can be fit into 818 1 times, resulting in a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 715 from 818 and we're left with 103.
Append the next digit (5) from the dividend to 103 and continue with: 1035 / 715

Going ahead to step 4:
If we divide 1035 by 715, we get 1 and a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 320 after subtracting 715 from 1035.
Take the next digit (8) from the dividend and append it to 320, then repeat: 3208 / 715

Let's proceed to step 5:
715 goes into 3208 4 times with a remainder of 348.
The next digit of our result is 4. 
Result so far: 114.0
The remainder is 348 after subtracting 2860 from 3208.
Bring next digit (7) of the dividend behind the 348 and repeat the process: 3487 / 715

Advancing to step 6:
When dividing 3487 by 715, we get 4 with a remainder of 627.
Put 4 as the next digit of the answer. 
Result so far: 1144.0
Subtracting 2860 from 3487 leaves us with 627.
Take the next digit (7) from the dividend and append it to 627, then repeat: 6277 / 715

Moving on to step 7:
715 goes into 6277 8 times with a remainder of 557.
The number 8 becomes the next digit in our result. 
Result so far: 11448.0
Subtract 5720 from 6277 to get 557.
Take the next digit (7) from the dividend and append it to 557, then repeat: 5577 / 715

Advancing to step 8:
715 can be fit into 5577 7 times, resulting in a remainder of 572.
The next digit of our result is 7. 
Result so far: 114487.0
If we take 5005 away from 5577, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 9:
715 goes into 5720 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 114487.8
If we take 5720 away from 5720, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 715 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 114487.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 715 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 114487.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 114487.8 and a remainder of 0.0.
