Let's divide 66045970 by 674
The aim is to understand the frequency of 674 in 66045970.

Advancing to step 1:
6 divided by 674 is 0 with 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.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 674

Advancing to step 2:
674 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 674

Moving on to step 3:
674 goes into 660 0 times with a remainder of 660.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 660, we end up with 660.
Bring next digit (4) of the dividend behind the 660 and repeat the process: 6604 / 674

On to step 4:
The number 674 fits into 6604 9 times, leaving a remainder of 538.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 6066 away from 6604, we end up with 538.
Include the next digit (5) from the dividend after 538, then repeat: 5385 / 674

Let's proceed to step 5:
When dividing 5385 by 674, we get 7 with a remainder of 667.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 4718 from 5385 and we're left with 667.
Bring next digit (9) of the dividend behind the 667 and repeat the process: 6679 / 674

Going ahead to step 6:
674 goes into 6679 9 times with a remainder of 613.
The next digit of our result is 9. 
Result so far: 979.0
Subtracting 6066 from 6679 leaves us with 613.
Take the next digit (7) from the dividend and append it to 613, then repeat: 6137 / 674

Going ahead to step 7:
When dividing 6137 by 674, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 9799.0
The remainder is 71 after subtracting 6066 from 6137.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 674

Going ahead to step 8:
674 goes into 710 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 97991.0
The remainder is 36 after subtracting 674 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
When dividing 360 by 674, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 97991.0
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
The number 674 fits into 3600 5 times, leaving a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 97991.05
Subtracting 3370 from 3600 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
If we divide 2300 by 674, we get 3 and a remainder of 278.
The next digit of our result is 3. 
Result so far: 97991.053
Subtract 2022 from 2300 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 12:
674 can be fit into 2780 4 times, resulting in a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 97991.0534
Subtract 2696 from 2780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
If we divide 840 by 674, we get 1 and a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 97991.05341
If we take 674 away from 840, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
The number 674 fits into 1660 2 times, leaving a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 97991.053412
If we take 1348 away from 1660, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 15:
674 goes into 3120 4 times with a remainder of 424.
Record the quotient 4 as the next digit in the result. 
Result so far: 97991.0534124
Subtract 2696 from 3120 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 16:
674 goes into 4240 6 times with a remainder of 196.
Record the quotient 6 as the next digit in the result. 
Result so far: 97991.05341246
The remainder is 196 after subtracting 4044 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 97991.05341246, with a leftover of 1.96e-07.
