98533400 ÷ 486 
The aim is to understand the frequency of 486 in 98533400.

Moving on to step 1:
The number 486 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 486

Advancing to step 2:
486 goes into 98 0 times with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 486

Step 3:
If we divide 985 by 486, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 972 from 985 and we're left with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 486

Moving on to step 4:
486 goes into 133 0 times with a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 133, we end up with 133.
Include the next digit (3) from the dividend after 133, then repeat: 1333 / 486

Moving on to step 5:
1333 divided by 486 is 2 with a remainder of 361.
The next digit of our result is 2. 
Result so far: 202.0
Subtract 972 from 1333 to get 361.
Bring next digit (4) of the dividend behind the 361 and repeat the process: 3614 / 486

Moving on to step 6:
3614 divided by 486 is 7 with a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 2027.0
If we subtract 3402 from 3614, we get 212.
Append the next digit (0) from the dividend to 212 and continue with: 2120 / 486

Step 7:
2120 divided by 486 is 4 with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 20274.0
The remainder is 176 after subtracting 1944 from 2120.
Take the next digit (0) from the dividend and append it to 176, then repeat: 1760 / 486

On to step 8:
If we divide 1760 by 486, we get 3 and a remainder of 302.
The next digit of our result is 3. 
Result so far: 202743.0
The remainder is 302 after subtracting 1458 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 9:
The number 486 fits into 3020 6 times, leaving a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 202743.6
If we take 2916 away from 3020, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
When dividing 1040 by 486, we get 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 202743.62
Subtracting 972 from 1040 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
486 can be fit into 680 1 times, resulting in a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 202743.621
If we take 486 away from 680, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 12:
486 can be fit into 1940 3 times, resulting in a remainder of 482.
The number 3 becomes the next digit in our result. 
Result so far: 202743.6213
Subtract 1458 from 1940 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 13:
486 goes into 4820 9 times with a remainder of 446.
Write down 9 as next digit of the result. 
Result so far: 202743.62139
Subtracting 4374 from 4820 leaves us 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.

On to step 14:
486 goes into 4460 9 times with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 202743.621399
Subtract 4374 from 4460 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 202743.621399 with a remainder of 8.6e-06.
