We're dividing 47223270 by 821 
The aim is to understand the frequency of 821 in 47223270.

Let's proceed to step 1:
821 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 821

Step 2:
821 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 821

On to step 3:
821 goes into 472 0 times with a remainder of 472.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 472 and we're left with 472.
Bring next digit (2) of the dividend behind the 472 and repeat the process: 4722 / 821

Step 4:
821 goes into 4722 5 times with a remainder of 617.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4105 from 4722 and we're left with 617.
Append the next digit (3) from the dividend to 617 and continue with: 6173 / 821

Advancing to step 5:
If we divide 6173 by 821, we get 7 and a remainder of 426.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 426 after subtracting 5747 from 6173.
Append the next digit (2) from the dividend to 426 and continue with: 4262 / 821

Let's proceed to step 6:
When dividing 4262 by 821, we get 5 with a remainder of 157.
Write down 5 as next digit of the result. 
Result so far: 575.0
Deduct 4105 from 4262 and we're left with 157.
Include the next digit (7) from the dividend after 157, then repeat: 1577 / 821

Going ahead to step 7:
If we divide 1577 by 821, we get 1 and a remainder of 756.
Use 1 as the next digit of our solution. 
Result so far: 5751.0
If we take 821 away from 1577, we end up with 756.
Include the next digit (0) from the dividend after 756, then repeat: 7560 / 821

Going ahead to step 8:
7560 divided by 821 is 9 with a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 57519.0
If we take 7389 away from 7560, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 9:
The number 821 fits into 1710 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 57519.2
Subtracting 1642 from 1710 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
The number 821 fits into 680 0 times, leaving a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 57519.2
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
The number 821 fits into 6800 8 times, leaving a remainder of 232.
The next digit of our result is 8. 
Result so far: 57519.208
The remainder is 232 after subtracting 6568 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
821 can be fit into 2320 2 times, resulting in a remainder of 678.
Put 2 as the next digit of the answer. 
Result so far: 57519.2082
Subtract 1642 from 2320 to get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Let's proceed to step 13:
When dividing 6780 by 821, we get 8 with a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 57519.20828
If we subtract 6568 from 6780, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 14:
If we divide 2120 by 821, we get 2 and a remainder of 478.
Use 2 as the next digit of our solution. 
Result so far: 57519.208282
Subtract 1642 from 2120 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 15:
4780 divided by 821 is 5 with a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 57519.2082825
Subtract 4105 from 4780 to get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 16:
6750 divided by 821 is 8 with a remainder of 182.
Put 8 as the next digit of the answer. 
Result so far: 57519.20828258
If we subtract 6568 from 6750, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 57519.20828258 and a remainder of 1.82e-07.
