74509417 divided by 411 
The aim is to understand the frequency of 411 in 74509417.

On to step 1:
When dividing 7 by 411, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 411

On to step 2:
If we divide 74 by 411, we get 0 and a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 411

Advancing to step 3:
If we divide 745 by 411, we get 1 and a remainder of 334.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 411 from 745 leaves us with 334.
Grab the next digit (0) from the dividend, add it to 334, then carry on: 3340 / 411

Going ahead to step 4:
When dividing 3340 by 411, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 52 after subtracting 3288 from 3340.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 411

On to step 5:
If we divide 529 by 411, we get 1 and a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 181.0
Subtracting 411 from 529 leaves us with 118.
Bring next digit (4) of the dividend behind the 118 and repeat the process: 1184 / 411

Going ahead to step 6:
411 can be fit into 1184 2 times, resulting in a remainder of 362.
Record the quotient 2 as the next digit in the result. 
Result so far: 1812.0
Deduct 822 from 1184 and we're left with 362.
Fetch the next digit (1) from the dividend, attach it to 362 and continue: 3621 / 411

Going ahead to step 7:
3621 divided by 411 is 8 with a remainder of 333.
Record the quotient 8 as the next digit in the result. 
Result so far: 18128.0
Subtract 3288 from 3621 to get 333.
Include the next digit (7) from the dividend after 333, then repeat: 3337 / 411

On to step 8:
411 goes into 3337 8 times with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 181288.0
Deduct 3288 from 3337 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
411 can be fit into 490 1 times, resulting in a remainder of 79.
The next digit of our result is 1. 
Result so far: 181288.1
Deduct 411 from 490 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
When dividing 790 by 411, we get 1 with a remainder of 379.
Write down 1 as next digit of the result. 
Result so far: 181288.11
The remainder is 379 after subtracting 411 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

The final outcome is 181288.11, with a leftover of 0.379.
