97621942 divided by 458 
The aim is to understand the frequency of 458 in 97621942.

Let's proceed to step 1:
458 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 458

Advancing to step 2:
If we divide 97 by 458, we get 0 and a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Grab the next digit (6) from the dividend, add it to 97, then carry on: 976 / 458

Let's proceed to step 3:
458 can be fit into 976 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 916 from 976 to get 60.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 458

On to step 4:
602 divided by 458 is 1 with a remainder of 144.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 144 after subtracting 458 from 602.
Bring next digit (1) of the dividend behind the 144 and repeat the process: 1441 / 458

Step 5:
If we divide 1441 by 458, we get 3 and a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtracting 1374 from 1441 leaves us with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 458

Advancing to step 6:
458 can be fit into 679 1 times, resulting in a remainder of 221.
Record the quotient 1 as the next digit in the result. 
Result so far: 2131.0
Subtract 458 from 679 to get 221.
Take the next digit (4) from the dividend and append it to 221, then repeat: 2214 / 458

Step 7:
458 goes into 2214 4 times with a remainder of 382.
The next digit of our result is 4. 
Result so far: 21314.0
Subtracting 1832 from 2214 leaves us with 382.
Fetch the next digit (2) from the dividend, attach it to 382 and continue: 3822 / 458

Advancing to step 8:
If we divide 3822 by 458, we get 8 and a remainder of 158.
The next digit of our result is 8. 
Result so far: 213148.0
Subtracting 3664 from 3822 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
1580 divided by 458 is 3 with a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 213148.3
If we take 1374 away from 1580, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 10:
458 can be fit into 2060 4 times, resulting in a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 213148.34
Subtract 1832 from 2060 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 11:
The number 458 fits into 2280 4 times, leaving a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 213148.344
If we take 1832 away from 2280, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

In conclusion, the division gives 213148.344 with a balance of 0.0448.
