75481164 ÷ 878 
The aim is to understand the frequency of 878 in 75481164.

Step 1:
If we divide 7 by 878, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 878

Advancing to step 2:
The number 878 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 878

Advancing to step 3:
When dividing 754 by 878, we get 0 with a remainder of 754.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 754 leaves us with 754.
Take the next digit (8) from the dividend and append it to 754, then repeat: 7548 / 878

Advancing to step 4:
If we divide 7548 by 878, we get 8 and a remainder of 524.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7024 from 7548 and we're left with 524.
Bring next digit (1) of the dividend behind the 524 and repeat the process: 5241 / 878

Let's proceed to step 5:
878 goes into 5241 5 times with a remainder of 851.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtracting 4390 from 5241 leaves us with 851.
Bring next digit (1) of the dividend behind the 851 and repeat the process: 8511 / 878

Going ahead to step 6:
The number 878 fits into 8511 9 times, leaving a remainder of 609.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Deduct 7902 from 8511 and we're left with 609.
Grab the next digit (6) from the dividend, add it to 609, then carry on: 6096 / 878

Let's proceed to step 7:
The number 878 fits into 6096 6 times, leaving a remainder of 828.
Put 6 as the next digit of the answer. 
Result so far: 8596.0
Subtract 5268 from 6096 to get 828.
Include the next digit (4) from the dividend after 828, then repeat: 8284 / 878

Moving on to step 8:
878 can be fit into 8284 9 times, resulting in a remainder of 382.
Record the quotient 9 as the next digit in the result. 
Result so far: 85969.0
If we take 7902 away from 8284, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 9:
878 goes into 3820 4 times with a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 85969.4
If we take 3512 away from 3820, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 10:
If we divide 3080 by 878, we get 3 and a remainder of 446.
The number 3 becomes the next digit in our result. 
Result so far: 85969.43
Deduct 2634 from 3080 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 11:
4460 divided by 878 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 85969.435
Subtract 4390 from 4460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
878 can be fit into 700 0 times, resulting in a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 85969.435
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 13:
If we divide 7000 by 878, we get 7 and a remainder of 854.
Record the quotient 7 as the next digit in the result. 
Result so far: 85969.43507
The remainder is 854 after subtracting 6146 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Advancing to step 14:
The number 878 fits into 8540 9 times, leaving a remainder of 638.
Use 9 as the next digit of our solution. 
Result so far: 85969.435079
If we subtract 7902 from 8540, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 15:
878 can be fit into 6380 7 times, resulting in a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 85969.4350797
Subtract 6146 from 6380 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 16:
The number 878 fits into 2340 2 times, leaving a remainder of 584.
Use 2 as the next digit of our solution. 
Result so far: 85969.43507972
Subtract 1756 from 2340 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

After the division, we end up with 85969.43507972 and a remainder of 5.84e-07.
