Let's divide 53613209 by 611
The aim is to understand the frequency of 611 in 53613209.

Step 1:
611 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 611

Going ahead to step 2:
611 goes into 53 0 times with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 611

Advancing to step 3:
If we divide 536 by 611, we get 0 and a remainder of 536.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 536 to get 536.
Grab the next digit (1) from the dividend, add it to 536, then carry on: 5361 / 611

Moving on to step 4:
5361 divided by 611 is 8 with a remainder of 473.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 4888 away from 5361, we end up with 473.
Take the next digit (3) from the dividend and append it to 473, then repeat: 4733 / 611

Going ahead to step 5:
611 can be fit into 4733 7 times, resulting in a remainder of 456.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 4277 from 4733 leaves us with 456.
Include the next digit (2) from the dividend after 456, then repeat: 4562 / 611

Let's proceed to step 6:
4562 divided by 611 is 7 with a remainder of 285.
Write down 7 as next digit of the result. 
Result so far: 877.0
If we subtract 4277 from 4562, we get 285.
Bring next digit (0) of the dividend behind the 285 and repeat the process: 2850 / 611

Step 7:
611 can be fit into 2850 4 times, resulting in a remainder of 406.
Write down 4 as next digit of the result. 
Result so far: 8774.0
Deduct 2444 from 2850 and we're left with 406.
Bring next digit (9) of the dividend behind the 406 and repeat the process: 4069 / 611

Step 8:
4069 divided by 611 is 6 with a remainder of 403.
Write down 6 as next digit of the result. 
Result so far: 87746.0
If we take 3666 away from 4069, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 9:
When dividing 4030 by 611, we get 6 with a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 87746.6
If we subtract 3666 from 4030, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 10:
If we divide 3640 by 611, we get 5 and a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 87746.65
Subtract 3055 from 3640 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Step 11:
5850 divided by 611 is 9 with a remainder of 351.
The next digit of our result is 9. 
Result so far: 87746.659
If we subtract 5499 from 5850, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 12:
611 goes into 3510 5 times with a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 87746.6595
Subtracting 3055 from 3510 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 13:
If we divide 4550 by 611, we get 7 and a remainder of 273.
Write down 7 as next digit of the result. 
Result so far: 87746.65957
If we take 4277 away from 4550, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 14:
611 can be fit into 2730 4 times, resulting in a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 87746.659574
If we subtract 2444 from 2730, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 15:
When dividing 2860 by 611, we get 4 with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 87746.6595744
Subtracting 2444 from 2860 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final outcome is 87746.6595744, with a leftover of 4.16e-06.
