We look at the division of 92100005 by 615 
The aim is to understand the frequency of 615 in 92100005.

Step 1:
If we divide 9 by 615, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 615

Step 2:
615 can be fit into 92 0 times, resulting in a remainder of 92.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 92, we end up with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 615

Let's proceed to step 3:
When dividing 921 by 615, we get 1 with a remainder of 306.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 615 from 921 leaves us with 306.
Fetch the next digit (0) from the dividend, attach it to 306 and continue: 3060 / 615

Going ahead to step 4:
3060 divided by 615 is 4 with a remainder of 600.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 600 after subtracting 2460 from 3060.
Grab the next digit (0) from the dividend, add it to 600, then carry on: 6000 / 615

Let's proceed to step 5:
615 can be fit into 6000 9 times, resulting in a remainder of 465.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 465 after subtracting 5535 from 6000.
Bring next digit (0) of the dividend behind the 465 and repeat the process: 4650 / 615

Let's proceed to step 6:
615 goes into 4650 7 times with a remainder of 345.
The number 7 becomes the next digit in our result. 
Result so far: 1497.0
Subtract 4305 from 4650 to get 345.
Include the next digit (0) from the dividend after 345, then repeat: 3450 / 615

On to step 7:
When dividing 3450 by 615, we get 5 with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 14975.0
Subtract 3075 from 3450 to get 375.
Grab the next digit (5) from the dividend, add it to 375, then carry on: 3755 / 615

Step 8:
615 can be fit into 3755 6 times, resulting in a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 149756.0
If we take 3690 away from 3755, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
The number 615 fits into 650 1 times, leaving a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 149756.1
If we take 615 away from 650, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
When dividing 350 by 615, we get 0 with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 149756.1
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
615 can be fit into 3500 5 times, resulting in a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 149756.105
Subtract 3075 from 3500 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 12:
When dividing 4250 by 615, we get 6 with a remainder of 560.
The next digit of our result is 6. 
Result so far: 149756.1056
The remainder is 560 after subtracting 3690 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
615 goes into 5600 9 times with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 149756.10569
If we subtract 5535 from 5600, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 14:
If we divide 650 by 615, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 149756.105691
The remainder is 35 after subtracting 615 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 15:
The number 615 fits into 350 0 times, leaving a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 149756.105691
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 16:
615 can be fit into 3500 5 times, resulting in a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 149756.10569105
Subtract 3075 from 3500 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The final result is 149756.10569105 with a remainder of 4.25e-07.
