We divide 18261213 by 394
The aim is to understand the frequency of 394 in 18261213.

Step 1:
1 divided by 394 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 394

Moving on to step 2:
When dividing 18 by 394, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 394

On to step 3:
When dividing 182 by 394, we get 0 with a remainder of 182.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 182 after subtracting 0 from 182.
Append the next digit (6) from the dividend to 182 and continue with: 1826 / 394

On to step 4:
The number 394 fits into 1826 4 times, leaving a remainder of 250.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1576 from 1826 to get 250.
Fetch the next digit (1) from the dividend, attach it to 250 and continue: 2501 / 394

Step 5:
2501 divided by 394 is 6 with a remainder of 137.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 2364 from 2501 leaves us with 137.
Take the next digit (2) from the dividend and append it to 137, then repeat: 1372 / 394

Step 6:
If we divide 1372 by 394, we get 3 and a remainder of 190.
The next digit of our result is 3. 
Result so far: 463.0
Deduct 1182 from 1372 and we're left with 190.
Grab the next digit (1) from the dividend, add it to 190, then carry on: 1901 / 394

Advancing to step 7:
394 can be fit into 1901 4 times, resulting in a remainder of 325.
Write down 4 as next digit of the result. 
Result so far: 4634.0
Subtract 1576 from 1901 to get 325.
Append the next digit (3) from the dividend to 325 and continue with: 3253 / 394

Advancing to step 8:
The number 394 fits into 3253 8 times, leaving a remainder of 101.
The next digit of our result is 8. 
Result so far: 46348.0
If we subtract 3152 from 3253, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
394 can be fit into 1010 2 times, resulting in a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 46348.2
If we subtract 788 from 1010, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 10:
394 can be fit into 2220 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 46348.25
Subtract 1970 from 2220 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
394 can be fit into 2500 6 times, resulting in a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 46348.256
If we subtract 2364 from 2500, we get 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 12:
The number 394 fits into 1360 3 times, leaving a remainder of 178.
Record the quotient 3 as the next digit in the result. 
Result so far: 46348.2563
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.

On to step 13:
The number 394 fits into 1780 4 times, leaving a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 46348.25634
If we take 1576 away from 1780, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 14:
When dividing 2040 by 394, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 46348.256345
Subtracting 1970 from 2040 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
The number 394 fits into 700 1 times, leaving a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 46348.2563451
If we subtract 394 from 700, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 16:
The number 394 fits into 3060 7 times, leaving a remainder of 302.
Record the quotient 7 as the next digit in the result. 
Result so far: 46348.25634517
If we subtract 2758 from 3060, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The final outcome is 46348.25634517, with a leftover of 3.02e-07.
