81192704 ÷ 386 
The aim is to understand the frequency of 386 in 81192704.

On to step 1:
386 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 386

On to step 2:
386 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 386

Step 3:
If we divide 811 by 386, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 772 from 811 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 386

Advancing to step 4:
386 goes into 399 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 386 from 399 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 386

Let's proceed to step 5:
The number 386 fits into 132 0 times, leaving a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we subtract 0 from 132, we get 132.
Bring next digit (7) of the dividend behind the 132 and repeat the process: 1327 / 386

Let's proceed to step 6:
The number 386 fits into 1327 3 times, leaving a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 2103.0
If we take 1158 away from 1327, we end up with 169.
Grab the next digit (0) from the dividend, add it to 169, then carry on: 1690 / 386

Let's proceed to step 7:
386 can be fit into 1690 4 times, resulting in a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 21034.0
The remainder is 146 after subtracting 1544 from 1690.
Grab the next digit (4) from the dividend, add it to 146, then carry on: 1464 / 386

Going ahead to step 8:
386 goes into 1464 3 times with a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 210343.0
If we subtract 1158 from 1464, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
3060 divided by 386 is 7 with a remainder of 358.
Write down 7 as next digit of the result. 
Result so far: 210343.7
The remainder is 358 after subtracting 2702 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 10:
The number 386 fits into 3580 9 times, leaving a remainder of 106.
The number 9 becomes the next digit in our result. 
Result so far: 210343.79
The remainder is 106 after subtracting 3474 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
If we divide 1060 by 386, we get 2 and a remainder of 288.
Record the quotient 2 as the next digit in the result. 
Result so far: 210343.792
Deduct 772 from 1060 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
If we divide 2880 by 386, we get 7 and a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 210343.7927
Subtract 2702 from 2880 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 13:
386 can be fit into 1780 4 times, resulting in a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 210343.79274
If we take 1544 away from 1780, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 14:
386 can be fit into 2360 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 210343.792746
Subtracting 2316 from 2360 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
440 divided by 386 is 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 210343.7927461
If we take 386 away from 440, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 16:
If we divide 540 by 386, we get 1 and a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 210343.79274611
The remainder is 154 after subtracting 386 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 210343.79274611 and a remainder of 1.54e-07.
