We look at the division of 611619 by 40 
The aim is to understand the frequency of 40 in 611619.

Going ahead to step 1:
40 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 40

On to step 2:
The number 40 fits into 61 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 40 from 61, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 40

Moving on to step 3:
When dividing 211 by 40, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 200 from 211, we get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 40

Advancing to step 4:
The number 40 fits into 116 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we take 80 away from 116, we end up with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 40

Let's proceed to step 5:
40 goes into 361 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1529.0
Deduct 360 from 361 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 40

On to step 6:
If we divide 19 by 40, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 15290.0
Subtract 0 from 19 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
If we divide 190 by 40, we get 4 and a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 15290.4
The remainder is 30 after subtracting 160 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 40 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 15290.47
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15290.475
Subtracting 200 from 200 leaves us 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.

On to step 10:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15290.475
Subtracting 0 from 0 leaves us 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.

Advancing to step 11:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15290.475
If we take 0 away from 0, 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.

The final outcome is 15290.475, with a leftover of 0.0.
