81758110 ÷ 386 
We want to figure out the number of times 81758110 can be divided by 386.

Advancing to step 1:
The number 386 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 386

Going ahead to step 2:
If we divide 81 by 386, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 386

Moving on to step 3:
When dividing 817 by 386, we get 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 772 from 817 leaves us with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 386

On to step 4:
455 divided by 386 is 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 386 from 455 and we're left with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 386

Let's proceed to step 5:
386 goes into 698 1 times with a remainder of 312.
The next digit of our result is 1. 
Result so far: 211.0
If we subtract 386 from 698, we get 312.
Take the next digit (1) from the dividend and append it to 312, then repeat: 3121 / 386

Advancing to step 6:
386 goes into 3121 8 times with a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 2118.0
The remainder is 33 after subtracting 3088 from 3121.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 386

Let's proceed to step 7:
386 can be fit into 331 0 times, resulting in a remainder of 331.
Put 0 as the next digit of the answer. 
Result so far: 21180.0
The remainder is 331 after subtracting 0 from 331.
Include the next digit (0) from the dividend after 331, then repeat: 3310 / 386

On to step 8:
If we divide 3310 by 386, we get 8 and a remainder of 222.
Write down 8 as next digit of the result. 
Result so far: 211808.0
If we take 3088 away from 3310, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 9:
386 can be fit into 2220 5 times, resulting in a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 211808.5
If we take 1930 away from 2220, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
The number 386 fits into 2900 7 times, leaving a remainder of 198.
Use 7 as the next digit of our solution. 
Result so far: 211808.57
If we subtract 2702 from 2900, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 11:
1980 divided by 386 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 211808.575
If we take 1930 away from 1980, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
When dividing 500 by 386, we get 1 with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 211808.5751
The remainder is 114 after subtracting 386 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 13:
When dividing 1140 by 386, we get 2 with a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 211808.57512
Subtract 772 from 1140 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 14:
When dividing 3680 by 386, we get 9 with a remainder of 206.
Use 9 as the next digit of our solution. 
Result so far: 211808.575129
Subtract 3474 from 3680 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 15:
When dividing 2060 by 386, we get 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 211808.5751295
Deduct 1930 from 2060 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
If we divide 1300 by 386, we get 3 and a remainder of 142.
Record the quotient 3 as the next digit in the result. 
Result so far: 211808.57512953
If we take 1158 away from 1300, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 211808.57512953 with a remainder of 1.42e-07.
