85360163 ÷ 921 
The aim is to understand the frequency of 921 in 85360163.

Step 1:
The number 921 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 921

Moving on to step 2:
The number 921 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Take the next digit (3) from the dividend and append it to 85, then repeat: 853 / 921

Going ahead to step 3:
853 divided by 921 is 0 with a remainder of 853.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 853, we get 853.
Include the next digit (6) from the dividend after 853, then repeat: 8536 / 921

On to step 4:
If we divide 8536 by 921, we get 9 and a remainder of 247.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 8289 from 8536 leaves us with 247.
Append the next digit (0) from the dividend to 247 and continue with: 2470 / 921

Moving on to step 5:
2470 divided by 921 is 2 with a remainder of 628.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 1842 from 2470, we get 628.
Take the next digit (1) from the dividend and append it to 628, then repeat: 6281 / 921

Moving on to step 6:
The number 921 fits into 6281 6 times, leaving a remainder of 755.
Record the quotient 6 as the next digit in the result. 
Result so far: 926.0
Subtracting 5526 from 6281 leaves us with 755.
Bring next digit (6) of the dividend behind the 755 and repeat the process: 7556 / 921

Moving on to step 7:
921 goes into 7556 8 times with a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 9268.0
Deduct 7368 from 7556 and we're left with 188.
Take the next digit (3) from the dividend and append it to 188, then repeat: 1883 / 921

On to step 8:
The number 921 fits into 1883 2 times, leaving a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 92682.0
Deduct 1842 from 1883 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
If we divide 410 by 921, we get 0 and a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 92682.0
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
4100 divided by 921 is 4 with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 92682.04
Deduct 3684 from 4100 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 11:
When dividing 4160 by 921, we get 4 with a remainder of 476.
Record the quotient 4 as the next digit in the result. 
Result so far: 92682.044
Subtracting 3684 from 4160 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

After the division, we end up with 92682.044 and a remainder of 0.0476.
