56640598 ÷ 446 
The aim is to understand the frequency of 446 in 56640598.

Step 1:
446 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 446

Advancing to step 2:
The number 446 fits into 56 0 times, leaving a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 446

Advancing to step 3:
The number 446 fits into 566 1 times, leaving a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 446 away from 566, we end up with 120.
Bring next digit (4) of the dividend behind the 120 and repeat the process: 1204 / 446

Let's proceed to step 4:
The number 446 fits into 1204 2 times, leaving a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 892 from 1204 and we're left with 312.
Append the next digit (0) from the dividend to 312 and continue with: 3120 / 446

Moving on to step 5:
446 can be fit into 3120 6 times, resulting in a remainder of 444.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 2676 from 3120 and we're left with 444.
Grab the next digit (5) from the dividend, add it to 444, then carry on: 4445 / 446

Advancing to step 6:
If we divide 4445 by 446, we get 9 and a remainder of 431.
Use 9 as the next digit of our solution. 
Result so far: 1269.0
If we take 4014 away from 4445, we end up with 431.
Take the next digit (9) from the dividend and append it to 431, then repeat: 4319 / 446

Moving on to step 7:
When dividing 4319 by 446, we get 9 with a remainder of 305.
The next digit of our result is 9. 
Result so far: 12699.0
If we take 4014 away from 4319, we end up with 305.
Append the next digit (8) from the dividend to 305 and continue with: 3058 / 446

Let's proceed to step 8:
When dividing 3058 by 446, we get 6 with a remainder of 382.
Write down 6 as next digit of the result. 
Result so far: 126996.0
The remainder is 382 after subtracting 2676 from 3058.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 9:
446 goes into 3820 8 times with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 126996.8
If we take 3568 away from 3820, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 10:
The number 446 fits into 2520 5 times, leaving a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 126996.85
The remainder is 290 after subtracting 2230 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 11:
If we divide 2900 by 446, we get 6 and a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 126996.856
If we subtract 2676 from 2900, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 12:
When dividing 2240 by 446, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 126996.8565
The remainder is 10 after subtracting 2230 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
446 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 126996.8565
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
When dividing 1000 by 446, we get 2 with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 126996.856502
Deduct 892 from 1000 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 15:
When dividing 1080 by 446, we get 2 with a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 126996.8565022
If we take 892 away from 1080, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final result is 126996.8565022 with a remainder of 1.88e-06.
