42171550 ÷ 386 
The aim is to understand the frequency of 386 in 42171550.

Advancing to step 1:
If we divide 4 by 386, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 386

Going ahead to step 2:
386 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 386

On to step 3:
If we divide 421 by 386, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 35 after subtracting 386 from 421.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 386

Advancing to step 4:
When dividing 357 by 386, we get 0 with a remainder of 357.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 357 to get 357.
Append the next digit (1) from the dividend to 357 and continue with: 3571 / 386

Moving on to step 5:
The number 386 fits into 3571 9 times, leaving a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtract 3474 from 3571 to get 97.
Take the next digit (5) from the dividend and append it to 97, then repeat: 975 / 386

Let's proceed to step 6:
When dividing 975 by 386, we get 2 with a remainder of 203.
Write down 2 as next digit of the result. 
Result so far: 1092.0
If we subtract 772 from 975, we get 203.
Bring next digit (5) of the dividend behind the 203 and repeat the process: 2035 / 386

Advancing to step 7:
386 can be fit into 2035 5 times, resulting in a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 10925.0
If we take 1930 away from 2035, we end up with 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 386

Advancing to step 8:
When dividing 1050 by 386, we get 2 with a remainder of 278.
The next digit of our result is 2. 
Result so far: 109252.0
Subtract 772 from 1050 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 9:
2780 divided by 386 is 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 109252.7
Deduct 2702 from 2780 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
386 can be fit into 780 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 109252.72
If we take 772 away from 780, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
386 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 109252.72
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 386, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 109252.7202
The remainder is 28 after subtracting 772 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
If we divide 280 by 386, we get 0 and a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 109252.7202
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
386 goes into 2800 7 times with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 109252.720207
Subtract 2702 from 2800 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 15:
980 divided by 386 is 2 with a remainder of 208.
The next digit of our result is 2. 
Result so far: 109252.7202072
Deduct 772 from 980 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 16:
2080 divided by 386 is 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 109252.72020725
Deduct 1930 from 2080 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 109252.72020725 and a remainder of 1.5e-07.
