90673215 ÷ 805 
The aim is to understand the frequency of 805 in 90673215.

Step 1:
805 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 805

Step 2:
90 divided by 805 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (6) from the dividend, add it to 90, then carry on: 906 / 805

Let's proceed to step 3:
The number 805 fits into 906 1 times, leaving a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 805 away from 906, we end up with 101.
Bring next digit (7) of the dividend behind the 101 and repeat the process: 1017 / 805

Let's proceed to step 4:
1017 divided by 805 is 1 with a remainder of 212.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 805 from 1017 and we're left with 212.
Fetch the next digit (3) from the dividend, attach it to 212 and continue: 2123 / 805

Advancing to step 5:
2123 divided by 805 is 2 with a remainder of 513.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtract 1610 from 2123 to get 513.
Grab the next digit (2) from the dividend, add it to 513, then carry on: 5132 / 805

Going ahead to step 6:
If we divide 5132 by 805, we get 6 and a remainder of 302.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
Deduct 4830 from 5132 and we're left with 302.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 805

Advancing to step 7:
The number 805 fits into 3021 3 times, leaving a remainder of 606.
Put 3 as the next digit of the answer. 
Result so far: 11263.0
Deduct 2415 from 3021 and we're left with 606.
Take the next digit (5) from the dividend and append it to 606, then repeat: 6065 / 805

Moving on to step 8:
If we divide 6065 by 805, we get 7 and a remainder of 430.
The next digit of our result is 7. 
Result so far: 112637.0
Subtract 5635 from 6065 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
When dividing 4300 by 805, we get 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 112637.5
Subtracting 4025 from 4300 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 10:
805 goes into 2750 3 times with a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 112637.53
Subtract 2415 from 2750 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 11:
805 can be fit into 3350 4 times, resulting in a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 112637.534
Subtracting 3220 from 3350 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
805 goes into 1300 1 times with a remainder of 495.
Record the quotient 1 as the next digit in the result. 
Result so far: 112637.5341
If we subtract 805 from 1300, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 13:
If we divide 4950 by 805, we get 6 and a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 112637.53416
Subtract 4830 from 4950 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
805 can be fit into 1200 1 times, resulting in a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 112637.534161
The remainder is 395 after subtracting 805 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 15:
805 goes into 3950 4 times with a remainder of 730.
Use 4 as the next digit of our solution. 
Result so far: 112637.5341614
If we subtract 3220 from 3950, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 16:
805 goes into 7300 9 times with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 112637.53416149
If we subtract 7245 from 7300, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 112637.53416149, and the remainder is 5.5e-08.
