We look at the division of 46378818 by 361 
The aim is to understand the frequency of 361 in 46378818.

Let's proceed to step 1:
361 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 361

Advancing to step 2:
361 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 361

Let's proceed to step 3:
361 goes into 463 1 times with a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 361 from 463, we get 102.
Grab the next digit (7) from the dividend, add it to 102, then carry on: 1027 / 361

Moving on to step 4:
If we divide 1027 by 361, we get 2 and a remainder of 305.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 722 from 1027, we get 305.
Include the next digit (8) from the dividend after 305, then repeat: 3058 / 361

Moving on to step 5:
If we divide 3058 by 361, we get 8 and a remainder of 170.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 2888 from 3058 leaves us with 170.
Take the next digit (8) from the dividend and append it to 170, then repeat: 1708 / 361

Moving on to step 6:
1708 divided by 361 is 4 with a remainder of 264.
The next digit of our result is 4. 
Result so far: 1284.0
Deduct 1444 from 1708 and we're left with 264.
Grab the next digit (1) from the dividend, add it to 264, then carry on: 2641 / 361

Moving on to step 7:
When dividing 2641 by 361, we get 7 with a remainder of 114.
The next digit of our result is 7. 
Result so far: 12847.0
Subtracting 2527 from 2641 leaves us with 114.
Append the next digit (8) from the dividend to 114 and continue with: 1148 / 361

Going ahead to step 8:
361 goes into 1148 3 times with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 128473.0
Subtract 1083 from 1148 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
When dividing 650 by 361, we get 1 with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 128473.1
Subtracting 361 from 650 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 10:
361 can be fit into 2890 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 128473.18
Subtracting 2888 from 2890 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 361 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 128473.18
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 361, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 128473.18
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 128473.18 and a remainder of 0.002.
