We're dividing 66716092 by 745 
The aim is to understand the frequency of 745 in 66716092.

On to step 1:
If we divide 6 by 745, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 745

Step 2:
745 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 745

Step 3:
If we divide 667 by 745, we get 0 and a remainder of 667.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 667 to get 667.
Bring next digit (1) of the dividend behind the 667 and repeat the process: 6671 / 745

Step 4:
745 goes into 6671 8 times with a remainder of 711.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 711 after subtracting 5960 from 6671.
Include the next digit (6) from the dividend after 711, then repeat: 7116 / 745

On to step 5:
7116 divided by 745 is 9 with a remainder of 411.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 6705 away from 7116, we end up with 411.
Append the next digit (0) from the dividend to 411 and continue with: 4110 / 745

Going ahead to step 6:
745 can be fit into 4110 5 times, resulting in a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 895.0
If we subtract 3725 from 4110, we get 385.
Grab the next digit (9) from the dividend, add it to 385, then carry on: 3859 / 745

Advancing to step 7:
745 can be fit into 3859 5 times, resulting in a remainder of 134.
Put 5 as the next digit of the answer. 
Result so far: 8955.0
Subtracting 3725 from 3859 leaves us with 134.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 745

Going ahead to step 8:
1342 divided by 745 is 1 with a remainder of 597.
Put 1 as the next digit of the answer. 
Result so far: 89551.0
If we subtract 745 from 1342, we get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Advancing to step 9:
When dividing 5970 by 745, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 89551.8
Subtract 5960 from 5970 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 745, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 89551.8
Deduct 0 from 100 and we're left 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.

Advancing to step 11:
If we divide 1000 by 745, we get 1 and a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 89551.801
Deduct 745 from 1000 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 12:
When dividing 2550 by 745, we get 3 with a remainder of 315.
Use 3 as the next digit of our solution. 
Result so far: 89551.8013
Subtracting 2235 from 2550 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 13:
When dividing 3150 by 745, we get 4 with a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 89551.80134
The remainder is 170 after subtracting 2980 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
The number 745 fits into 1700 2 times, leaving a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 89551.801342
The remainder is 210 after subtracting 1490 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 15:
745 goes into 2100 2 times with a remainder of 610.
Use 2 as the next digit of our solution. 
Result so far: 89551.8013422
The remainder is 610 after subtracting 1490 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The final outcome is 89551.8013422, with a leftover of 6.1e-06.
