81395973 ÷ 379 
The aim is to understand the frequency of 379 in 81395973.

Going ahead to step 1:
379 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 379

On to step 2:
81 divided by 379 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 379

Going ahead to step 3:
379 can be fit into 813 2 times, resulting in a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 55 after subtracting 758 from 813.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 379

Going ahead to step 4:
559 divided by 379 is 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 379 from 559, we get 180.
Grab the next digit (5) from the dividend, add it to 180, then carry on: 1805 / 379

On to step 5:
379 can be fit into 1805 4 times, resulting in a remainder of 289.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
If we take 1516 away from 1805, we end up with 289.
Append the next digit (9) from the dividend to 289 and continue with: 2899 / 379

Let's proceed to step 6:
The number 379 fits into 2899 7 times, leaving a remainder of 246.
Record the quotient 7 as the next digit in the result. 
Result so far: 2147.0
Deduct 2653 from 2899 and we're left with 246.
Fetch the next digit (7) from the dividend, attach it to 246 and continue: 2467 / 379

On to step 7:
379 can be fit into 2467 6 times, resulting in a remainder of 193.
Put 6 as the next digit of the answer. 
Result so far: 21476.0
If we take 2274 away from 2467, we end up with 193.
Include the next digit (3) from the dividend after 193, then repeat: 1933 / 379

On to step 8:
The number 379 fits into 1933 5 times, leaving a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 214765.0
The remainder is 38 after subtracting 1895 from 1933.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
When dividing 380 by 379, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 214765.1
If we take 379 away from 380, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
10 divided by 379 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 214765.1
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 379, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 214765.1
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 214765.1, and the remainder is 0.01.
