86410123 ÷ 363 
The aim is to understand the frequency of 363 in 86410123.

Step 1:
363 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 363

Let's proceed to step 2:
The number 363 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 363

On to step 3:
363 goes into 864 2 times with a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 726 away from 864, we end up with 138.
Take the next digit (1) from the dividend and append it to 138, then repeat: 1381 / 363

Advancing to step 4:
When dividing 1381 by 363, we get 3 with a remainder of 292.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 1089 away from 1381, we end up with 292.
Bring next digit (0) of the dividend behind the 292 and repeat the process: 2920 / 363

Moving on to step 5:
363 goes into 2920 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Subtracting 2904 from 2920 leaves us with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 363

Let's proceed to step 6:
363 can be fit into 161 0 times, resulting in a remainder of 161.
Put 0 as the next digit of the answer. 
Result so far: 2380.0
Subtract 0 from 161 to get 161.
Include the next digit (2) from the dividend after 161, then repeat: 1612 / 363

Advancing to step 7:
363 goes into 1612 4 times with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 23804.0
Subtract 1452 from 1612 to get 160.
Bring next digit (3) of the dividend behind the 160 and repeat the process: 1603 / 363

Advancing to step 8:
1603 divided by 363 is 4 with a remainder of 151.
Record the quotient 4 as the next digit in the result. 
Result so far: 238044.0
The remainder is 151 after subtracting 1452 from 1603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 9:
363 goes into 1510 4 times with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 238044.4
If we subtract 1452 from 1510, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
If we divide 580 by 363, we get 1 and a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 238044.41
Deduct 363 from 580 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 11:
If we divide 2170 by 363, we get 5 and a remainder of 355.
The number 5 becomes the next digit in our result. 
Result so far: 238044.415
Subtract 1815 from 2170 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 12:
When dividing 3550 by 363, we get 9 with a remainder of 283.
Put 9 as the next digit of the answer. 
Result so far: 238044.4159
If we subtract 3267 from 3550, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 13:
363 can be fit into 2830 7 times, resulting in a remainder of 289.
The next digit of our result is 7. 
Result so far: 238044.41597
If we take 2541 away from 2830, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Advancing to step 14:
363 goes into 2890 7 times with a remainder of 349.
The next digit of our result is 7. 
Result so far: 238044.415977
Subtracting 2541 from 2890 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The quotient of the division is 238044.415977, and the remainder is 3.49e-05.
