We're dividing 70958563 by 458 
The aim is to understand the frequency of 458 in 70958563.

Step 1:
458 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 458

Advancing to step 2:
When dividing 70 by 458, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 458

Moving on to step 3:
458 can be fit into 709 1 times, resulting in a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 458 from 709 leaves us with 251.
Append the next digit (5) from the dividend to 251 and continue with: 2515 / 458

On to step 4:
458 can be fit into 2515 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2290 from 2515 to get 225.
Fetch the next digit (8) from the dividend, attach it to 225 and continue: 2258 / 458

Going ahead to step 5:
458 can be fit into 2258 4 times, resulting in a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we take 1832 away from 2258, we end up with 426.
Fetch the next digit (5) from the dividend, attach it to 426 and continue: 4265 / 458

Step 6:
458 goes into 4265 9 times with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 1549.0
Subtracting 4122 from 4265 leaves us with 143.
Grab the next digit (6) from the dividend, add it to 143, then carry on: 1436 / 458

Moving on to step 7:
458 goes into 1436 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 15493.0
Deduct 1374 from 1436 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 458

On to step 8:
When dividing 623 by 458, we get 1 with a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 154931.0
Deduct 458 from 623 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 9:
1650 divided by 458 is 3 with a remainder of 276.
Put 3 as the next digit of the answer. 
Result so far: 154931.3
Subtracting 1374 from 1650 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 10:
When dividing 2760 by 458, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 154931.36
If we subtract 2748 from 2760, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 458 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 154931.36
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 458 fits into 1200 2 times, leaving a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 154931.3602
Subtracting 916 from 1200 leaves us with 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 13:
458 can be fit into 2840 6 times, resulting in a remainder of 92.
The next digit of our result is 6. 
Result so far: 154931.36026
Deduct 2748 from 2840 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 14:
When dividing 920 by 458, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 154931.360262
If we subtract 916 from 920, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
40 divided by 458 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 154931.360262
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
458 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 154931.360262
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 154931.360262, with a leftover of 4e-07.
