Let's divide 83733294 by 821
The aim is to understand the frequency of 821 in 83733294.

Moving on to step 1:
821 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 821

Let's proceed to step 2:
The number 821 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 821

Advancing to step 3:
821 can be fit into 837 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 821 from 837, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 821

On to step 4:
821 can be fit into 163 0 times, resulting in a remainder of 163.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 163 to get 163.
Fetch the next digit (3) from the dividend, attach it to 163 and continue: 1633 / 821

Let's proceed to step 5:
821 can be fit into 1633 1 times, resulting in a remainder of 812.
The next digit of our result is 1. 
Result so far: 101.0
If we take 821 away from 1633, we end up with 812.
Grab the next digit (2) from the dividend, add it to 812, then carry on: 8122 / 821

On to step 6:
When dividing 8122 by 821, we get 9 with a remainder of 733.
Put 9 as the next digit of the answer. 
Result so far: 1019.0
Subtract 7389 from 8122 to get 733.
Grab the next digit (9) from the dividend, add it to 733, then carry on: 7339 / 821

Step 7:
The number 821 fits into 7339 8 times, leaving a remainder of 771.
Use 8 as the next digit of our solution. 
Result so far: 10198.0
If we take 6568 away from 7339, we end up with 771.
Grab the next digit (4) from the dividend, add it to 771, then carry on: 7714 / 821

Moving on to step 8:
7714 divided by 821 is 9 with a remainder of 325.
Write down 9 as next digit of the result. 
Result so far: 101989.0
The remainder is 325 after subtracting 7389 from 7714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 9:
821 can be fit into 3250 3 times, resulting in a remainder of 787.
Record the quotient 3 as the next digit in the result. 
Result so far: 101989.3
Subtracting 2463 from 3250 leaves us with 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Step 10:
The number 821 fits into 7870 9 times, leaving a remainder of 481.
The number 9 becomes the next digit in our result. 
Result so far: 101989.39
Subtract 7389 from 7870 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 11:
The number 821 fits into 4810 5 times, leaving a remainder of 705.
Write down 5 as next digit of the result. 
Result so far: 101989.395
If we subtract 4105 from 4810, we get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 12:
The number 821 fits into 7050 8 times, leaving a remainder of 482.
The number 8 becomes the next digit in our result. 
Result so far: 101989.3958
If we take 6568 away from 7050, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 13:
When dividing 4820 by 821, we get 5 with a remainder of 715.
Write down 5 as next digit of the result. 
Result so far: 101989.39585
Subtract 4105 from 4820 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Going ahead to step 14:
If we divide 7150 by 821, we get 8 and a remainder of 582.
Write down 8 as next digit of the result. 
Result so far: 101989.395858
Deduct 6568 from 7150 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 15:
5820 divided by 821 is 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 101989.3958587
If we take 5747 away from 5820, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 16:
When dividing 730 by 821, we get 0 with a remainder of 730.
Write down 0 as next digit of the result. 
Result so far: 101989.3958587
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

After the division, we end up with 101989.3958587 and a remainder of 7.3e-07.
