94303389 ÷ 661 
The aim is to understand the frequency of 661 in 94303389.

Step 1:
When dividing 9 by 661, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 661

Step 2:
The number 661 fits into 94 0 times, leaving a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 94, we end up with 94.
Take the next digit (3) from the dividend and append it to 94, then repeat: 943 / 661

Step 3:
When dividing 943 by 661, we get 1 with a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 661 from 943 to get 282.
Take the next digit (0) from the dividend and append it to 282, then repeat: 2820 / 661

Advancing to step 4:
The number 661 fits into 2820 4 times, leaving a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2644 from 2820, we get 176.
Take the next digit (3) from the dividend and append it to 176, then repeat: 1763 / 661

Advancing to step 5:
661 can be fit into 1763 2 times, resulting in a remainder of 441.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we take 1322 away from 1763, we end up with 441.
Fetch the next digit (3) from the dividend, attach it to 441 and continue: 4413 / 661

Advancing to step 6:
When dividing 4413 by 661, we get 6 with a remainder of 447.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
The remainder is 447 after subtracting 3966 from 4413.
Take the next digit (8) from the dividend and append it to 447, then repeat: 4478 / 661

Let's proceed to step 7:
4478 divided by 661 is 6 with a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 14266.0
Deduct 3966 from 4478 and we're left with 512.
Take the next digit (9) from the dividend and append it to 512, then repeat: 5129 / 661

Advancing to step 8:
If we divide 5129 by 661, we get 7 and a remainder of 502.
Put 7 as the next digit of the answer. 
Result so far: 142667.0
Subtract 4627 from 5129 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 9:
661 goes into 5020 7 times with a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 142667.7
Deduct 4627 from 5020 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 10:
3930 divided by 661 is 5 with a remainder of 625.
Put 5 as the next digit of the answer. 
Result so far: 142667.75
The remainder is 625 after subtracting 3305 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 11:
If we divide 6250 by 661, we get 9 and a remainder of 301.
The number 9 becomes the next digit in our result. 
Result so far: 142667.759
The remainder is 301 after subtracting 5949 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 12:
3010 divided by 661 is 4 with a remainder of 366.
Record the quotient 4 as the next digit in the result. 
Result so far: 142667.7594
Subtracting 2644 from 3010 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 13:
When dividing 3660 by 661, we get 5 with a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 142667.75945
Deduct 3305 from 3660 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 14:
661 goes into 3550 5 times with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 142667.759455
Deduct 3305 from 3550 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final outcome is 142667.759455, with a leftover of 2.45e-05.
