393787 ÷ 43 
We want to figure out the number of times 393787 can be divided by 43.

Going ahead to step 1:
When dividing 3 by 43, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 43

Moving on to step 2:
43 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 43

Advancing to step 3:
393 divided by 43 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 387 from 393, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 43

Step 4:
The number 43 fits into 67 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 43 from 67, we get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 43

Advancing to step 5:
43 can be fit into 248 5 times, resulting in a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 915.0
Subtract 215 from 248 to get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 43

Advancing to step 6:
If we divide 337 by 43, we get 7 and a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 9157.0
Subtracting 301 from 337 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 43, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 9157.8
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
43 can be fit into 160 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 9157.83
Deduct 129 from 160 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 43 fits into 310 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 9157.837
The remainder is 9 after subtracting 301 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
90 divided by 43 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 9157.8372
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 43 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9157.8372
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 43, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 9157.837209
If we subtract 387 from 400, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
130 divided by 43 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 9157.8372093
Deduct 129 from 130 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
If we divide 10 by 43, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 9157.8372093
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 9157.8372093 with a remaining 1e-08.
