45718302 ÷ 381 
The aim is to understand the frequency of 381 in 45718302.

Going ahead to step 1:
381 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
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 381

Let's proceed to step 2:
If we divide 45 by 381, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 381

Advancing to step 3:
457 divided by 381 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 381 from 457 leaves us with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 381

On to step 4:
381 goes into 761 1 times with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 380 after subtracting 381 from 761.
Bring next digit (8) of the dividend behind the 380 and repeat the process: 3808 / 381

Moving on to step 5:
The number 381 fits into 3808 9 times, leaving a remainder of 379.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
The remainder is 379 after subtracting 3429 from 3808.
Append the next digit (3) from the dividend to 379 and continue with: 3793 / 381

Let's proceed to step 6:
3793 divided by 381 is 9 with a remainder of 364.
The next digit of our result is 9. 
Result so far: 1199.0
If we subtract 3429 from 3793, we get 364.
Bring next digit (0) of the dividend behind the 364 and repeat the process: 3640 / 381

Moving on to step 7:
When dividing 3640 by 381, we get 9 with a remainder of 211.
The number 9 becomes the next digit in our result. 
Result so far: 11999.0
Subtracting 3429 from 3640 leaves us with 211.
Fetch the next digit (2) from the dividend, attach it to 211 and continue: 2112 / 381

On to step 8:
If we divide 2112 by 381, we get 5 and a remainder of 207.
Write down 5 as next digit of the result. 
Result so far: 119995.0
Subtract 1905 from 2112 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
If we divide 2070 by 381, we get 5 and a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 119995.5
Subtract 1905 from 2070 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
1650 divided by 381 is 4 with a remainder of 126.
The next digit of our result is 4. 
Result so far: 119995.54
Subtracting 1524 from 1650 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
381 can be fit into 1260 3 times, resulting in a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 119995.543
Deduct 1143 from 1260 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 12:
When dividing 1170 by 381, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 119995.5433
Subtracting 1143 from 1170 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 119995.5433 and a remainder of 0.00027.
