59266233 ÷ 409 
The aim is to understand the frequency of 409 in 59266233.

On to step 1:
409 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 409

On to step 2:
59 divided by 409 is 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Include the next digit (2) from the dividend after 59, then repeat: 592 / 409

Step 3:
409 can be fit into 592 1 times, resulting in a remainder of 183.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 409 from 592 and we're left with 183.
Take the next digit (6) from the dividend and append it to 183, then repeat: 1836 / 409

Moving on to step 4:
1836 divided by 409 is 4 with a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1636 from 1836 and we're left with 200.
Take the next digit (6) from the dividend and append it to 200, then repeat: 2006 / 409

Step 5:
2006 divided by 409 is 4 with a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Subtract 1636 from 2006 to get 370.
Take the next digit (2) from the dividend and append it to 370, then repeat: 3702 / 409

Advancing to step 6:
The number 409 fits into 3702 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 1449.0
The remainder is 21 after subtracting 3681 from 3702.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 409

Advancing to step 7:
213 divided by 409 is 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 14490.0
Subtract 0 from 213 to get 213.
Grab the next digit (3) from the dividend, add it to 213, then carry on: 2133 / 409

Step 8:
2133 divided by 409 is 5 with a remainder of 88.
Put 5 as the next digit of the answer. 
Result so far: 144905.0
If we subtract 2045 from 2133, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
If we divide 880 by 409, we get 2 and a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 144905.2
Subtracting 818 from 880 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
If we divide 620 by 409, we get 1 and a remainder of 211.
The number 1 becomes the next digit in our result. 
Result so far: 144905.21
If we take 409 away from 620, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 11:
The number 409 fits into 2110 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 144905.215
If we take 2045 away from 2110, 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 12:
650 divided by 409 is 1 with a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 144905.2151
Subtracting 409 from 650 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 13:
When dividing 2410 by 409, we get 5 with a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 144905.21515
Subtracting 2045 from 2410 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 14:
3650 divided by 409 is 8 with a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 144905.215158
If we subtract 3272 from 3650, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 15:
409 goes into 3780 9 times with a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 144905.2151589
The remainder is 99 after subtracting 3681 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 16:
409 goes into 990 2 times with a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 144905.21515892
Deduct 818 from 990 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 144905.21515892 and a remainder of 1.72e-07.
