Let's divide 89331779 by 394
The aim is to understand the frequency of 394 in 89331779.

On to step 1:
When dividing 8 by 394, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 394

On to step 2:
89 divided by 394 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Bring next digit (3) of the dividend behind the 89 and repeat the process: 893 / 394

Going ahead to step 3:
When dividing 893 by 394, we get 2 with a remainder of 105.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 788 from 893 and we're left with 105.
Include the next digit (3) from the dividend after 105, then repeat: 1053 / 394

Moving on to step 4:
1053 divided by 394 is 2 with a remainder of 265.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 788 from 1053, we get 265.
Take the next digit (1) from the dividend and append it to 265, then repeat: 2651 / 394

Advancing to step 5:
When dividing 2651 by 394, we get 6 with a remainder of 287.
The next digit of our result is 6. 
Result so far: 226.0
If we subtract 2364 from 2651, we get 287.
Bring next digit (7) of the dividend behind the 287 and repeat the process: 2877 / 394

Going ahead to step 6:
2877 divided by 394 is 7 with a remainder of 119.
Record the quotient 7 as the next digit in the result. 
Result so far: 2267.0
Deduct 2758 from 2877 and we're left with 119.
Fetch the next digit (7) from the dividend, attach it to 119 and continue: 1197 / 394

Let's proceed to step 7:
When dividing 1197 by 394, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 22673.0
If we take 1182 away from 1197, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 394

Step 8:
159 divided by 394 is 0 with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 226730.0
Subtracting 0 from 159 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
The number 394 fits into 1590 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 226730.4
Subtracting 1576 from 1590 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 394 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 226730.4
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
When dividing 1400 by 394, we get 3 with a remainder of 218.
Put 3 as the next digit of the answer. 
Result so far: 226730.403
Subtract 1182 from 1400 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 12:
The number 394 fits into 2180 5 times, leaving a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 226730.4035
Subtract 1970 from 2180 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 13:
The number 394 fits into 2100 5 times, leaving a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 226730.40355
Subtracting 1970 from 2100 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 226730.40355, with a leftover of 0.00013.
