56349491 ÷ 448 
The aim is to understand the frequency of 448 in 56349491.

Going ahead to step 1:
If we divide 5 by 448, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 448

Moving on to step 2:
448 goes into 56 0 times with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 448

Advancing to step 3:
The number 448 fits into 563 1 times, leaving a remainder of 115.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 448 from 563, we get 115.
Grab the next digit (4) from the dividend, add it to 115, then carry on: 1154 / 448

Moving on to step 4:
448 goes into 1154 2 times with a remainder of 258.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 896 from 1154, we get 258.
Grab the next digit (9) from the dividend, add it to 258, then carry on: 2589 / 448

On to step 5:
448 can be fit into 2589 5 times, resulting in a remainder of 349.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtract 2240 from 2589 to get 349.
Bring next digit (4) of the dividend behind the 349 and repeat the process: 3494 / 448

On to step 6:
If we divide 3494 by 448, we get 7 and a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 1257.0
The remainder is 358 after subtracting 3136 from 3494.
Take the next digit (9) from the dividend and append it to 358, then repeat: 3589 / 448

Moving on to step 7:
When dividing 3589 by 448, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 12578.0
If we take 3584 away from 3589, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 448

Step 8:
448 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 125780.0
If we take 0 away from 51, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
When dividing 510 by 448, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 125780.1
If we subtract 448 from 510, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
620 divided by 448 is 1 with a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 125780.11
Subtract 448 from 620 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 125780.11, with a leftover of 0.172.
