We look at the division of 78901496 by 285 
The aim is to understand the frequency of 285 in 78901496.

Advancing to step 1:
285 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 285

Moving on to step 2:
The number 285 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 285

On to step 3:
789 divided by 285 is 2 with a remainder of 219.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 570 from 789, we get 219.
Append the next digit (0) from the dividend to 219 and continue with: 2190 / 285

Advancing to step 4:
285 can be fit into 2190 7 times, resulting in a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 195 after subtracting 1995 from 2190.
Bring next digit (1) of the dividend behind the 195 and repeat the process: 1951 / 285

Step 5:
If we divide 1951 by 285, we get 6 and a remainder of 241.
Put 6 as the next digit of the answer. 
Result so far: 276.0
Deduct 1710 from 1951 and we're left with 241.
Take the next digit (4) from the dividend and append it to 241, then repeat: 2414 / 285

Advancing to step 6:
2414 divided by 285 is 8 with a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 2768.0
Subtract 2280 from 2414 to get 134.
Append the next digit (9) from the dividend to 134 and continue with: 1349 / 285

Going ahead to step 7:
When dividing 1349 by 285, we get 4 with a remainder of 209.
Record the quotient 4 as the next digit in the result. 
Result so far: 27684.0
The remainder is 209 after subtracting 1140 from 1349.
Take the next digit (6) from the dividend and append it to 209, then repeat: 2096 / 285

Step 8:
When dividing 2096 by 285, we get 7 with a remainder of 101.
Record the quotient 7 as the next digit in the result. 
Result so far: 276847.0
If we subtract 1995 from 2096, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
The number 285 fits into 1010 3 times, leaving a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 276847.3
Subtract 855 from 1010 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 10:
When dividing 1550 by 285, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 276847.35
If we take 1425 away from 1550, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 11:
The number 285 fits into 1250 4 times, leaving a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 276847.354
The remainder is 110 after subtracting 1140 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
When dividing 1100 by 285, we get 3 with a remainder of 245.
Write down 3 as next digit of the result. 
Result so far: 276847.3543
Subtract 855 from 1100 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 13:
285 goes into 2450 8 times with a remainder of 170.
Put 8 as the next digit of the answer. 
Result so far: 276847.35438
The remainder is 170 after subtracting 2280 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
285 can be fit into 1700 5 times, resulting in a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 276847.354385
If we take 1425 away from 1700, we end up 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.

Advancing to step 15:
285 can be fit into 2750 9 times, resulting in a remainder of 185.
Write down 9 as next digit of the result. 
Result so far: 276847.3543859
If we take 2565 away from 2750, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 16:
If we divide 1850 by 285, we get 6 and a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 276847.35438596
Subtracting 1710 from 1850 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 276847.35438596, and the remainder is 1.4e-07.
