We look at the division of 59117389 by 821 
The aim is to understand the frequency of 821 in 59117389.

Advancing to step 1:
821 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 821

Advancing to step 2:
59 divided by 821 is 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 821

Moving on to step 3:
821 can be fit into 591 0 times, resulting in a remainder of 591.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 591, we end up with 591.
Bring next digit (1) of the dividend behind the 591 and repeat the process: 5911 / 821

Step 4:
821 can be fit into 5911 7 times, resulting in a remainder of 164.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5747 away from 5911, we end up with 164.
Bring next digit (7) of the dividend behind the 164 and repeat the process: 1647 / 821

Advancing to step 5:
If we divide 1647 by 821, we get 2 and a remainder of 5.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 1642 from 1647 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 821

Let's proceed to step 6:
The number 821 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
If we subtract 0 from 53, we get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 821

On to step 7:
If we divide 538 by 821, we get 0 and a remainder of 538.
Use 0 as the next digit of our solution. 
Result so far: 7200.0
Subtract 0 from 538 to get 538.
Append the next digit (9) from the dividend to 538 and continue with: 5389 / 821

Let's proceed to step 8:
821 can be fit into 5389 6 times, resulting in a remainder of 463.
Write down 6 as next digit of the result. 
Result so far: 72006.0
Subtract 4926 from 5389 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 9:
821 can be fit into 4630 5 times, resulting in a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 72006.5
Deduct 4105 from 4630 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 10:
When dividing 5250 by 821, we get 6 with a remainder of 324.
The next digit of our result is 6. 
Result so far: 72006.56
Subtract 4926 from 5250 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 11:
3240 divided by 821 is 3 with a remainder of 777.
Record the quotient 3 as the next digit in the result. 
Result so far: 72006.563
If we subtract 2463 from 3240, we get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Moving on to step 12:
821 goes into 7770 9 times with a remainder of 381.
The number 9 becomes the next digit in our result. 
Result so far: 72006.5639
If we take 7389 away from 7770, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 13:
821 can be fit into 3810 4 times, resulting in a remainder of 526.
Record the quotient 4 as the next digit in the result. 
Result so far: 72006.56394
Subtracting 3284 from 3810 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 14:
821 goes into 5260 6 times with a remainder of 334.
Use 6 as the next digit of our solution. 
Result so far: 72006.563946
Subtracting 4926 from 5260 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 15:
When dividing 3340 by 821, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 72006.5639464
If we take 3284 away from 3340, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
When dividing 560 by 821, we get 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 72006.5639464
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The quotient of the division is 72006.5639464, and the remainder is 5.6e-07.
