42058850 divided by 486 
The aim is to understand the frequency of 486 in 42058850.

Step 1:
4 divided by 486 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 486

Moving on to step 2:
If we divide 42 by 486, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 486

Let's proceed to step 3:
486 can be fit into 420 0 times, resulting in a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 420 after subtracting 0 from 420.
Append the next digit (5) from the dividend to 420 and continue with: 4205 / 486

Let's proceed to step 4:
486 can be fit into 4205 8 times, resulting in a remainder of 317.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 3888 from 4205 leaves us with 317.
Include the next digit (8) from the dividend after 317, then repeat: 3178 / 486

Moving on to step 5:
If we divide 3178 by 486, we get 6 and a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 2916 from 3178, we get 262.
Take the next digit (8) from the dividend and append it to 262, then repeat: 2628 / 486

Advancing to step 6:
The number 486 fits into 2628 5 times, leaving a remainder of 198.
The next digit of our result is 5. 
Result so far: 865.0
Subtracting 2430 from 2628 leaves us with 198.
Include the next digit (5) from the dividend after 198, then repeat: 1985 / 486

Going ahead to step 7:
When dividing 1985 by 486, we get 4 with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 8654.0
Subtracting 1944 from 1985 leaves us with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 486

Moving on to step 8:
When dividing 410 by 486, we get 0 with a remainder of 410.
The next digit of our result is 0. 
Result so far: 86540.0
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 9:
486 goes into 4100 8 times with a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 86540.8
Deduct 3888 from 4100 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
If we divide 2120 by 486, we get 4 and a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 86540.84
The remainder is 176 after subtracting 1944 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
If we divide 1760 by 486, we get 3 and a remainder of 302.
Write down 3 as next digit of the result. 
Result so far: 86540.843
If we subtract 1458 from 1760, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 12:
If we divide 3020 by 486, we get 6 and a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 86540.8436
If we subtract 2916 from 3020, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 13:
The number 486 fits into 1040 2 times, leaving a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 86540.84362
If we subtract 972 from 1040, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
486 goes into 680 1 times with a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 86540.843621
The remainder is 194 after subtracting 486 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 15:
When dividing 1940 by 486, we get 3 with a remainder of 482.
Write down 3 as next digit of the result. 
Result so far: 86540.8436213
If we take 1458 away from 1940, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 16:
If we divide 4820 by 486, we get 9 and a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 86540.84362139
If we subtract 4374 from 4820, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Our division results in 86540.84362139 with a remaining 4.46e-07.
