We divide 10640535 by 921
The aim is to understand the frequency of 921 in 10640535.

Moving on to step 1:
921 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 921

On to step 2:
The number 921 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 921

On to step 3:
If we divide 106 by 921, we get 0 and a remainder of 106.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 106 leaves us with 106.
Take the next digit (4) from the dividend and append it to 106, then repeat: 1064 / 921

Moving on to step 4:
921 can be fit into 1064 1 times, resulting in a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 921 from 1064 leaves us with 143.
Append the next digit (0) from the dividend to 143 and continue with: 1430 / 921

Going ahead to step 5:
If we divide 1430 by 921, we get 1 and a remainder of 509.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 921 from 1430, we get 509.
Grab the next digit (5) from the dividend, add it to 509, then carry on: 5095 / 921

Let's proceed to step 6:
921 can be fit into 5095 5 times, resulting in a remainder of 490.
The next digit of our result is 5. 
Result so far: 115.0
If we take 4605 away from 5095, we end up with 490.
Append the next digit (3) from the dividend to 490 and continue with: 4903 / 921

On to step 7:
921 can be fit into 4903 5 times, resulting in a remainder of 298.
Put 5 as the next digit of the answer. 
Result so far: 1155.0
Subtracting 4605 from 4903 leaves us with 298.
Take the next digit (5) from the dividend and append it to 298, then repeat: 2985 / 921

Going ahead to step 8:
If we divide 2985 by 921, we get 3 and a remainder of 222.
The number 3 becomes the next digit in our result. 
Result so far: 11553.0
Subtracting 2763 from 2985 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 9:
921 can be fit into 2220 2 times, resulting in a remainder of 378.
The number 2 becomes the next digit in our result. 
Result so far: 11553.2
Deduct 1842 from 2220 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 10:
3780 divided by 921 is 4 with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 11553.24
Subtracting 3684 from 3780 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
When dividing 960 by 921, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 11553.241
If we take 921 away from 960, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
921 can be fit into 390 0 times, resulting in a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 11553.241
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 13:
3900 divided by 921 is 4 with a remainder of 216.
The next digit of our result is 4. 
Result so far: 11553.24104
If we subtract 3684 from 3900, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 14:
If we divide 2160 by 921, we get 2 and a remainder of 318.
The number 2 becomes the next digit in our result. 
Result so far: 11553.241042
Subtract 1842 from 2160 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 15:
921 can be fit into 3180 3 times, resulting in a remainder of 417.
Record the quotient 3 as the next digit in the result. 
Result so far: 11553.2410423
If we subtract 2763 from 3180, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Step 16:
921 can be fit into 4170 4 times, resulting in a remainder of 486.
Write down 4 as next digit of the result. 
Result so far: 11553.24104234
Subtracting 3684 from 4170 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

The final outcome is 11553.24104234, with a leftover of 4.86e-07.
