21602765 divided by 891 
The aim is to understand the frequency of 891 in 21602765.

On to step 1:
When dividing 2 by 891, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 891

Moving on to step 2:
When dividing 21 by 891, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 891

Let's proceed to step 3:
891 can be fit into 216 0 times, resulting in a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Append the next digit (0) from the dividend to 216 and continue with: 2160 / 891

Going ahead to step 4:
If we divide 2160 by 891, we get 2 and a remainder of 378.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1782 from 2160 and we're left with 378.
Fetch the next digit (2) from the dividend, attach it to 378 and continue: 3782 / 891

Advancing to step 5:
If we divide 3782 by 891, we get 4 and a remainder of 218.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 3564 away from 3782, we end up with 218.
Fetch the next digit (7) from the dividend, attach it to 218 and continue: 2187 / 891

Going ahead to step 6:
If we divide 2187 by 891, we get 2 and a remainder of 405.
Record the quotient 2 as the next digit in the result. 
Result so far: 242.0
If we take 1782 away from 2187, we end up with 405.
Append the next digit (6) from the dividend to 405 and continue with: 4056 / 891

Step 7:
The number 891 fits into 4056 4 times, leaving a remainder of 492.
The number 4 becomes the next digit in our result. 
Result so far: 2424.0
Subtracting 3564 from 4056 leaves us with 492.
Grab the next digit (5) from the dividend, add it to 492, then carry on: 4925 / 891

Step 8:
891 goes into 4925 5 times with a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 24245.0
If we subtract 4455 from 4925, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 9:
When dividing 4700 by 891, we get 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 24245.5
Subtracting 4455 from 4700 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 10:
When dividing 2450 by 891, we get 2 with a remainder of 668.
Write down 2 as next digit of the result. 
Result so far: 24245.52
If we take 1782 away from 2450, we end up with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 11:
891 can be fit into 6680 7 times, resulting in a remainder of 443.
Put 7 as the next digit of the answer. 
Result so far: 24245.527
Subtracting 6237 from 6680 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Let's proceed to step 12:
4430 divided by 891 is 4 with a remainder of 866.
Use 4 as the next digit of our solution. 
Result so far: 24245.5274
If we subtract 3564 from 4430, we get 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Let's proceed to step 13:
891 goes into 8660 9 times with a remainder of 641.
Put 9 as the next digit of the answer. 
Result so far: 24245.52749
If we subtract 8019 from 8660, we get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Let's proceed to step 14:
When dividing 6410 by 891, we get 7 with a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 24245.527497
Deduct 6237 from 6410 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 15:
When dividing 1730 by 891, we get 1 with a remainder of 839.
Record the quotient 1 as the next digit in the result. 
Result so far: 24245.5274971
Subtract 891 from 1730 to get 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

On to step 16:
The number 891 fits into 8390 9 times, leaving a remainder of 371.
Write down 9 as next digit of the result. 
Result so far: 24245.52749719
If we subtract 8019 from 8390, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Our division results in 24245.52749719 with a remaining 3.71e-07.
