We divide 45723709 by 819
The aim is to understand the frequency of 819 in 45723709.

On to step 1:
819 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 819

Step 2:
819 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 819

On to step 3:
457 divided by 819 is 0 with a remainder of 457.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 457 to get 457.
Grab the next digit (2) from the dividend, add it to 457, then carry on: 4572 / 819

Advancing to step 4:
819 can be fit into 4572 5 times, resulting in a remainder of 477.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4095 from 4572 to get 477.
Append the next digit (3) from the dividend to 477 and continue with: 4773 / 819

Advancing to step 5:
819 can be fit into 4773 5 times, resulting in a remainder of 678.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Deduct 4095 from 4773 and we're left with 678.
Append the next digit (7) from the dividend to 678 and continue with: 6787 / 819

Advancing to step 6:
6787 divided by 819 is 8 with a remainder of 235.
Put 8 as the next digit of the answer. 
Result so far: 558.0
The remainder is 235 after subtracting 6552 from 6787.
Bring next digit (0) of the dividend behind the 235 and repeat the process: 2350 / 819

Let's proceed to step 7:
When dividing 2350 by 819, we get 2 with a remainder of 712.
The next digit of our result is 2. 
Result so far: 5582.0
Deduct 1638 from 2350 and we're left with 712.
Include the next digit (9) from the dividend after 712, then repeat: 7129 / 819

Let's proceed to step 8:
When dividing 7129 by 819, we get 8 with a remainder of 577.
The next digit of our result is 8. 
Result so far: 55828.0
The remainder is 577 after subtracting 6552 from 7129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 9:
819 goes into 5770 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 55828.7
If we take 5733 away from 5770, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
The number 819 fits into 370 0 times, leaving a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 55828.7
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 11:
819 can be fit into 3700 4 times, resulting in a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 55828.704
Subtracting 3276 from 3700 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 12:
If we divide 4240 by 819, we get 5 and a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 55828.7045
Subtracting 4095 from 4240 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 13:
819 goes into 1450 1 times with a remainder of 631.
The next digit of our result is 1. 
Result so far: 55828.70451
Subtracting 819 from 1450 leaves us with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Moving on to step 14:
The number 819 fits into 6310 7 times, leaving a remainder of 577.
Use 7 as the next digit of our solution. 
Result so far: 55828.704517
If we subtract 5733 from 6310, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 15:
The number 819 fits into 5770 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 55828.7045177
Deduct 5733 from 5770 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 55828.7045177 and a remainder of 3.7e-07.
