Let's divide 50229643 by 745
The aim is to understand the frequency of 745 in 50229643.

Going ahead to step 1:
If we divide 5 by 745, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 745

Step 2:
50 divided by 745 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 745

Moving on to step 3:
745 can be fit into 502 0 times, resulting in a remainder of 502.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 502 leaves us with 502.
Take the next digit (2) from the dividend and append it to 502, then repeat: 5022 / 745

On to step 4:
745 goes into 5022 6 times with a remainder of 552.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4470 from 5022, we get 552.
Append the next digit (9) from the dividend to 552 and continue with: 5529 / 745

Let's proceed to step 5:
745 goes into 5529 7 times with a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
The remainder is 314 after subtracting 5215 from 5529.
Take the next digit (6) from the dividend and append it to 314, then repeat: 3146 / 745

Moving on to step 6:
745 goes into 3146 4 times with a remainder of 166.
The number 4 becomes the next digit in our result. 
Result so far: 674.0
Deduct 2980 from 3146 and we're left with 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 745

Step 7:
745 can be fit into 1664 2 times, resulting in a remainder of 174.
Record the quotient 2 as the next digit in the result. 
Result so far: 6742.0
Subtract 1490 from 1664 to get 174.
Fetch the next digit (3) from the dividend, attach it to 174 and continue: 1743 / 745

Going ahead to step 8:
When dividing 1743 by 745, we get 2 with a remainder of 253.
The next digit of our result is 2. 
Result so far: 67422.0
If we take 1490 away from 1743, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 9:
When dividing 2530 by 745, we get 3 with a remainder of 295.
Use 3 as the next digit of our solution. 
Result so far: 67422.3
Subtracting 2235 from 2530 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 10:
When dividing 2950 by 745, we get 3 with a remainder of 715.
Put 3 as the next digit of the answer. 
Result so far: 67422.33
The remainder is 715 after subtracting 2235 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

After the division, we end up with 67422.33 and a remainder of 0.715.
