Let's divide 75778038 by 394
The aim is to understand the frequency of 394 in 75778038.

Advancing to step 1:
7 divided by 394 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 394

On to step 2:
When dividing 75 by 394, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 394

On to step 3:
When dividing 757 by 394, we get 1 with a remainder of 363.
The next digit of our result is 1. 
Result so far: 1.0
If we take 394 away from 757, we end up with 363.
Include the next digit (7) from the dividend after 363, then repeat: 3637 / 394

Let's proceed to step 4:
When dividing 3637 by 394, we get 9 with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 3546 from 3637 to get 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 394

Step 5:
The number 394 fits into 918 2 times, leaving a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 192.0
If we take 788 away from 918, we end up with 130.
Fetch the next digit (0) from the dividend, attach it to 130 and continue: 1300 / 394

On to step 6:
If we divide 1300 by 394, we get 3 and a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 1923.0
The remainder is 118 after subtracting 1182 from 1300.
Take the next digit (3) from the dividend and append it to 118, then repeat: 1183 / 394

Moving on to step 7:
1183 divided by 394 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 19233.0
Deduct 1182 from 1183 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 394

Moving on to step 8:
When dividing 18 by 394, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 192330.0
If we take 0 away from 18, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
394 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 192330.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 394, we get 4 with a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 192330.04
Subtracting 1576 from 1800 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 11:
2240 divided by 394 is 5 with a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 192330.045
If we subtract 1970 from 2240, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 12:
When dividing 2700 by 394, we get 6 with a remainder of 336.
The next digit of our result is 6. 
Result so far: 192330.0456
If we take 2364 away from 2700, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 13:
394 goes into 3360 8 times with a remainder of 208.
The next digit of our result is 8. 
Result so far: 192330.04568
Subtract 3152 from 3360 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 14:
The number 394 fits into 2080 5 times, leaving a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 192330.045685
If we subtract 1970 from 2080, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
1100 divided by 394 is 2 with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 192330.0456852
Deduct 788 from 1100 and we're left 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.

Going ahead to step 16:
394 goes into 3120 7 times with a remainder of 362.
Record the quotient 7 as the next digit in the result. 
Result so far: 192330.04568527
If we take 2758 away from 3120, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The quotient of the division is 192330.04568527, and the remainder is 3.62e-07.
