74399410 ÷ 878 
The aim is to understand the frequency of 878 in 74399410.

Step 1:
The number 878 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 878

Step 2:
The number 878 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 878

Advancing to step 3:
743 divided by 878 is 0 with a remainder of 743.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 743 leaves us with 743.
Grab the next digit (9) from the dividend, add it to 743, then carry on: 7439 / 878

Advancing to step 4:
When dividing 7439 by 878, we get 8 with a remainder of 415.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7024 from 7439, we get 415.
Take the next digit (9) from the dividend and append it to 415, then repeat: 4159 / 878

Going ahead to step 5:
4159 divided by 878 is 4 with a remainder of 647.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 3512 from 4159, we get 647.
Take the next digit (4) from the dividend and append it to 647, then repeat: 6474 / 878

Step 6:
If we divide 6474 by 878, we get 7 and a remainder of 328.
The number 7 becomes the next digit in our result. 
Result so far: 847.0
Deduct 6146 from 6474 and we're left with 328.
Bring next digit (1) of the dividend behind the 328 and repeat the process: 3281 / 878

Going ahead to step 7:
When dividing 3281 by 878, we get 3 with a remainder of 647.
Write down 3 as next digit of the result. 
Result so far: 8473.0
If we take 2634 away from 3281, we end up with 647.
Bring next digit (0) of the dividend behind the 647 and repeat the process: 6470 / 878

Let's proceed to step 8:
The number 878 fits into 6470 7 times, leaving a remainder of 324.
The next digit of our result is 7. 
Result so far: 84737.0
Subtracting 6146 from 6470 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 9:
If we divide 3240 by 878, we get 3 and a remainder of 606.
The next digit of our result is 3. 
Result so far: 84737.3
Deduct 2634 from 3240 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 10:
If we divide 6060 by 878, we get 6 and a remainder of 792.
The next digit of our result is 6. 
Result so far: 84737.36
Subtracting 5268 from 6060 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 11:
878 can be fit into 7920 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 84737.369
If we take 7902 away from 7920, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
878 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 84737.369
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
The number 878 fits into 1800 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 84737.36902
If we take 1756 away from 1800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
440 divided by 878 is 0 with a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 84737.36902
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 15:
The number 878 fits into 4400 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 84737.3690205
Subtract 4390 from 4400 to 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.

Going ahead to step 16:
878 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 84737.3690205
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 84737.3690205 with a remaining 1e-07.
