73019453 ÷ 381 
The aim is to understand the frequency of 381 in 73019453.

Step 1:
7 divided by 381 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 381

On to step 2:
381 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 381

Going ahead to step 3:
The number 381 fits into 730 1 times, leaving a remainder of 349.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 349 after subtracting 381 from 730.
Append the next digit (1) from the dividend to 349 and continue with: 3491 / 381

Advancing to step 4:
When dividing 3491 by 381, we get 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 3429 from 3491, we get 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 381

On to step 5:
If we divide 629 by 381, we get 1 and a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 191.0
If we take 381 away from 629, we end up with 248.
Fetch the next digit (4) from the dividend, attach it to 248 and continue: 2484 / 381

On to step 6:
When dividing 2484 by 381, we get 6 with a remainder of 198.
Write down 6 as next digit of the result. 
Result so far: 1916.0
Subtracting 2286 from 2484 leaves us with 198.
Fetch the next digit (5) from the dividend, attach it to 198 and continue: 1985 / 381

On to step 7:
The number 381 fits into 1985 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 19165.0
Deduct 1905 from 1985 and we're left with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 381

Let's proceed to step 8:
381 goes into 803 2 times with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 191652.0
Subtracting 762 from 803 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
381 can be fit into 410 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 191652.1
Subtract 381 from 410 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
290 divided by 381 is 0 with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 191652.1
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 11:
381 goes into 2900 7 times with a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 191652.107
Deduct 2667 from 2900 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 12:
381 goes into 2330 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 191652.1076
Deduct 2286 from 2330 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
381 goes into 440 1 times with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 191652.10761
Subtract 381 from 440 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 14:
When dividing 590 by 381, we get 1 with a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 191652.107611
If we subtract 381 from 590, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

After the division, we end up with 191652.107611 and a remainder of 2.09e-05.
