We're dividing 3458991 by 446 
The aim is to understand the frequency of 446 in 3458991.

Going ahead to step 1:
446 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 446

Let's proceed to step 2:
When dividing 34 by 446, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 446

Going ahead to step 3:
If we divide 345 by 446, we get 0 and a remainder of 345.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 345 after subtracting 0 from 345.
Bring next digit (8) of the dividend behind the 345 and repeat the process: 3458 / 446

On to step 4:
If we divide 3458 by 446, we get 7 and a remainder of 336.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 3122 from 3458, we get 336.
Append the next digit (9) from the dividend to 336 and continue with: 3369 / 446

Step 5:
446 can be fit into 3369 7 times, resulting in a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 3122 from 3369, we get 247.
Fetch the next digit (9) from the dividend, attach it to 247 and continue: 2479 / 446

Moving on to step 6:
2479 divided by 446 is 5 with a remainder of 249.
Record the quotient 5 as the next digit in the result. 
Result so far: 775.0
The remainder is 249 after subtracting 2230 from 2479.
Take the next digit (1) from the dividend and append it to 249, then repeat: 2491 / 446

Step 7:
446 goes into 2491 5 times with a remainder of 261.
Write down 5 as next digit of the result. 
Result so far: 7755.0
Deduct 2230 from 2491 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 8:
2610 divided by 446 is 5 with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 7755.5
Deduct 2230 from 2610 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 9:
3800 divided by 446 is 8 with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 7755.58
If we take 3568 away from 3800, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 10:
When dividing 2320 by 446, we get 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 7755.585
The remainder is 90 after subtracting 2230 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
When dividing 900 by 446, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7755.5852
If we subtract 892 from 900, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
446 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 7755.5852
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
446 can be fit into 800 1 times, resulting in a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 7755.585201
Subtracting 446 from 800 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 14:
446 goes into 3540 7 times with a remainder of 418.
The number 7 becomes the next digit in our result. 
Result so far: 7755.5852017
If we subtract 3122 from 3540, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 15:
446 can be fit into 4180 9 times, resulting in a remainder of 166.
Write down 9 as next digit of the result. 
Result so far: 7755.58520179
Subtracting 4014 from 4180 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The quotient of the division is 7755.58520179, and the remainder is 1.66e-07.
