We look at the division of 40534818 by 615 
The aim is to understand the frequency of 615 in 40534818.

On to step 1:
615 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 615

Advancing to step 2:
When dividing 40 by 615, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 615

On to step 3:
The number 615 fits into 405 0 times, leaving a remainder of 405.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 405 to get 405.
Include the next digit (3) from the dividend after 405, then repeat: 4053 / 615

Advancing to step 4:
615 can be fit into 4053 6 times, resulting in a remainder of 363.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3690 from 4053, we get 363.
Include the next digit (4) from the dividend after 363, then repeat: 3634 / 615

On to step 5:
If we divide 3634 by 615, we get 5 and a remainder of 559.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 3075 from 3634 to get 559.
Bring next digit (8) of the dividend behind the 559 and repeat the process: 5598 / 615

Going ahead to step 6:
When dividing 5598 by 615, we get 9 with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
If we subtract 5535 from 5598, we get 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 615

Moving on to step 7:
631 divided by 615 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 6591.0
The remainder is 16 after subtracting 615 from 631.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 615

Let's proceed to step 8:
615 goes into 168 0 times with a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 65910.0
Deduct 0 from 168 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
If we divide 1680 by 615, we get 2 and a remainder of 450.
The next digit of our result is 2. 
Result so far: 65910.2
Subtracting 1230 from 1680 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
615 can be fit into 4500 7 times, resulting in a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 65910.27
If we take 4305 away from 4500, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 11:
615 can be fit into 1950 3 times, resulting in a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 65910.273
Subtract 1845 from 1950 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
1050 divided by 615 is 1 with a remainder of 435.
Use 1 as the next digit of our solution. 
Result so far: 65910.2731
Subtracting 615 from 1050 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 13:
4350 divided by 615 is 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 65910.27317
Subtracting 4305 from 4350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
615 can be fit into 450 0 times, resulting in a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 65910.27317
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
615 can be fit into 4500 7 times, resulting in a remainder of 195.
The number 7 becomes the next digit in our result. 
Result so far: 65910.2731707
Subtracting 4305 from 4500 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 16:
615 can be fit into 1950 3 times, resulting in a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 65910.27317073
Deduct 1845 from 1950 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 65910.27317073 with a remaining 1.05e-07.
