86878443 divided by 753 
The aim is to understand the frequency of 753 in 86878443.

Let's proceed to step 1:
8 divided by 753 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 753

Advancing to step 2:
753 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 753

Going ahead to step 3:
If we divide 868 by 753, we get 1 and a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 753 from 868, we get 115.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 753

Moving on to step 4:
If we divide 1157 by 753, we get 1 and a remainder of 404.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 753 from 1157, we get 404.
Take the next digit (8) from the dividend and append it to 404, then repeat: 4048 / 753

On to step 5:
753 can be fit into 4048 5 times, resulting in a remainder of 283.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtract 3765 from 4048 to get 283.
Grab the next digit (4) from the dividend, add it to 283, then carry on: 2834 / 753

Let's proceed to step 6:
2834 divided by 753 is 3 with a remainder of 575.
The next digit of our result is 3. 
Result so far: 1153.0
The remainder is 575 after subtracting 2259 from 2834.
Bring next digit (4) of the dividend behind the 575 and repeat the process: 5754 / 753

Moving on to step 7:
5754 divided by 753 is 7 with a remainder of 483.
Write down 7 as next digit of the result. 
Result so far: 11537.0
If we take 5271 away from 5754, we end up with 483.
Append the next digit (3) from the dividend to 483 and continue with: 4833 / 753

Step 8:
The number 753 fits into 4833 6 times, leaving a remainder of 315.
Put 6 as the next digit of the answer. 
Result so far: 115376.0
The remainder is 315 after subtracting 4518 from 4833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 9:
The number 753 fits into 3150 4 times, leaving a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 115376.4
The remainder is 138 after subtracting 3012 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 10:
1380 divided by 753 is 1 with a remainder of 627.
The next digit of our result is 1. 
Result so far: 115376.41
Subtracting 753 from 1380 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Moving on to step 11:
The number 753 fits into 6270 8 times, leaving a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 115376.418
If we subtract 6024 from 6270, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 12:
753 can be fit into 2460 3 times, resulting in a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 115376.4183
Deduct 2259 from 2460 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 13:
2010 divided by 753 is 2 with a remainder of 504.
The next digit of our result is 2. 
Result so far: 115376.41832
Subtracting 1506 from 2010 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 14:
753 can be fit into 5040 6 times, resulting in a remainder of 522.
Write down 6 as next digit of the result. 
Result so far: 115376.418326
If we subtract 4518 from 5040, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 15:
When dividing 5220 by 753, we get 6 with a remainder of 702.
Use 6 as the next digit of our solution. 
Result so far: 115376.4183266
The remainder is 702 after subtracting 4518 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

The final result is 115376.4183266 with a remainder of 7.02e-06.
