85912 ÷ 69 
The aim is to understand the frequency of 69 in 85912.

Moving on to step 1:
The number 69 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 69

Moving on to step 2:
If we divide 85 by 69, we get 1 and a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 69 from 85 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 69

On to step 3:
169 divided by 69 is 2 with a remainder of 31.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 138 from 169 and we're left with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 69

Advancing to step 4:
If we divide 311 by 69, we get 4 and a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtract 276 from 311 to get 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 69

Going ahead to step 5:
If we divide 352 by 69, we get 5 and a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 1245.0
Subtracting 345 from 352 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
If we divide 70 by 69, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1245.1
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
69 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1245.1
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 69 fits into 100 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1245.101
Deduct 69 from 100 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
When dividing 310 by 69, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 1245.1014
Deduct 276 from 310 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
When dividing 340 by 69, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 1245.10144
If we take 276 away from 340, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 1245.10144, and the remainder is 6.4e-05.
