We're dividing 80091269 by 921 
The aim is to understand the frequency of 921 in 80091269.

Advancing to step 1:
8 divided by 921 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 921

Advancing to step 2:
When dividing 80 by 921, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 921

Advancing to step 3:
When dividing 800 by 921, we get 0 with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 800 leaves us with 800.
Take the next digit (9) from the dividend and append it to 800, then repeat: 8009 / 921

On to step 4:
921 goes into 8009 8 times with a remainder of 641.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7368 away from 8009, we end up with 641.
Bring next digit (1) of the dividend behind the 641 and repeat the process: 6411 / 921

Moving on to step 5:
921 goes into 6411 6 times with a remainder of 885.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we take 5526 away from 6411, we end up with 885.
Take the next digit (2) from the dividend and append it to 885, then repeat: 8852 / 921

Let's proceed to step 6:
8852 divided by 921 is 9 with a remainder of 563.
Use 9 as the next digit of our solution. 
Result so far: 869.0
Subtracting 8289 from 8852 leaves us with 563.
Append the next digit (6) from the dividend to 563 and continue with: 5636 / 921

Let's proceed to step 7:
The number 921 fits into 5636 6 times, leaving a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 8696.0
Subtracting 5526 from 5636 leaves us with 110.
Append the next digit (9) from the dividend to 110 and continue with: 1109 / 921

Going ahead to step 8:
If we divide 1109 by 921, we get 1 and a remainder of 188.
Use 1 as the next digit of our solution. 
Result so far: 86961.0
The remainder is 188 after subtracting 921 from 1109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 9:
If we divide 1880 by 921, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 86961.2
Subtract 1842 from 1880 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
921 goes into 380 0 times with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 86961.2
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
The number 921 fits into 3800 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 86961.204
Deduct 3684 from 3800 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 12:
The number 921 fits into 1160 1 times, leaving a remainder of 239.
The next digit of our result is 1. 
Result so far: 86961.2041
Subtracting 921 from 1160 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 13:
921 can be fit into 2390 2 times, resulting in a remainder of 548.
Use 2 as the next digit of our solution. 
Result so far: 86961.20412
The remainder is 548 after subtracting 1842 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 14:
The number 921 fits into 5480 5 times, leaving a remainder of 875.
The number 5 becomes the next digit in our result. 
Result so far: 86961.204125
Subtracting 4605 from 5480 leaves us with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Let's proceed to step 15:
When dividing 8750 by 921, we get 9 with a remainder of 461.
The number 9 becomes the next digit in our result. 
Result so far: 86961.2041259
Subtract 8289 from 8750 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 16:
The number 921 fits into 4610 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 86961.20412595
Deduct 4605 from 4610 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 86961.20412595 with a remaining 5e-09.
