We're dividing 85904858 by 412 
The aim is to understand the frequency of 412 in 85904858.

Step 1:
The number 412 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 412

On to step 2:
412 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 412

On to step 3:
859 divided by 412 is 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 824 away from 859, we end up with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 412

On to step 4:
350 divided by 412 is 0 with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 350 and we're left with 350.
Take the next digit (4) from the dividend and append it to 350, then repeat: 3504 / 412

On to step 5:
If we divide 3504 by 412, we get 8 and a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Deduct 3296 from 3504 and we're left with 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 412

Let's proceed to step 6:
If we divide 2088 by 412, we get 5 and a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 2085.0
If we take 2060 away from 2088, we end up with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 412

On to step 7:
When dividing 285 by 412, we get 0 with a remainder of 285.
The next digit of our result is 0. 
Result so far: 20850.0
Subtract 0 from 285 to get 285.
Include the next digit (8) from the dividend after 285, then repeat: 2858 / 412

Advancing to step 8:
When dividing 2858 by 412, we get 6 with a remainder of 386.
Write down 6 as next digit of the result. 
Result so far: 208506.0
If we subtract 2472 from 2858, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
If we divide 3860 by 412, we get 9 and a remainder of 152.
The next digit of our result is 9. 
Result so far: 208506.9
Subtract 3708 from 3860 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
412 can be fit into 1520 3 times, resulting in a remainder of 284.
The next digit of our result is 3. 
Result so far: 208506.93
If we subtract 1236 from 1520, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 11:
When dividing 2840 by 412, we get 6 with a remainder of 368.
The next digit of our result is 6. 
Result so far: 208506.936
The remainder is 368 after subtracting 2472 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 12:
When dividing 3680 by 412, we get 8 with a remainder of 384.
Write down 8 as next digit of the result. 
Result so far: 208506.9368
Deduct 3296 from 3680 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 13:
412 can be fit into 3840 9 times, resulting in a remainder of 132.
Use 9 as the next digit of our solution. 
Result so far: 208506.93689
Subtract 3708 from 3840 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
The number 412 fits into 1320 3 times, leaving a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 208506.936893
Subtract 1236 from 1320 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
If we divide 840 by 412, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 208506.9368932
The remainder is 16 after subtracting 824 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
If we divide 160 by 412, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 208506.9368932
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 208506.9368932, with a leftover of 1.6e-07.
