50315118 ÷ 394 
The aim is to understand the frequency of 394 in 50315118.

Step 1:
The number 394 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 394

Let's proceed to step 2:
If we divide 50 by 394, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 394

Going ahead to step 3:
394 goes into 503 1 times with a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 394 from 503 to get 109.
Bring next digit (1) of the dividend behind the 109 and repeat the process: 1091 / 394

Let's proceed to step 4:
The number 394 fits into 1091 2 times, leaving a remainder of 303.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 788 from 1091 to get 303.
Grab the next digit (5) from the dividend, add it to 303, then carry on: 3035 / 394

Moving on to step 5:
3035 divided by 394 is 7 with a remainder of 277.
The next digit of our result is 7. 
Result so far: 127.0
The remainder is 277 after subtracting 2758 from 3035.
Grab the next digit (1) from the dividend, add it to 277, then carry on: 2771 / 394

Moving on to step 6:
2771 divided by 394 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1277.0
Subtract 2758 from 2771 to get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 394

Step 7:
394 goes into 131 0 times with a remainder of 131.
The next digit of our result is 0. 
Result so far: 12770.0
If we take 0 away from 131, we end up with 131.
Include the next digit (8) from the dividend after 131, then repeat: 1318 / 394

Going ahead to step 8:
When dividing 1318 by 394, we get 3 with a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 127703.0
Deduct 1182 from 1318 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 9:
If we divide 1360 by 394, we get 3 and a remainder of 178.
Record the quotient 3 as the next digit in the result. 
Result so far: 127703.3
If we take 1182 away from 1360, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 10:
394 can be fit into 1780 4 times, resulting in a remainder of 204.
Record the quotient 4 as the next digit in the result. 
Result so far: 127703.34
Subtract 1576 from 1780 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 11:
394 can be fit into 2040 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 127703.345
If we subtract 1970 from 2040, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
If we divide 700 by 394, we get 1 and a remainder of 306.
Use 1 as the next digit of our solution. 
Result so far: 127703.3451
The remainder is 306 after subtracting 394 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 13:
394 goes into 3060 7 times with a remainder of 302.
Record the quotient 7 as the next digit in the result. 
Result so far: 127703.34517
Deduct 2758 from 3060 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 14:
When dividing 3020 by 394, we get 7 with a remainder of 262.
Record the quotient 7 as the next digit in the result. 
Result so far: 127703.345177
Subtracting 2758 from 3020 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

After the division, we end up with 127703.345177 and a remainder of 2.62e-05.
