91173366 ÷ 43 
Our goal is to divide 91173366 by 43.

On to step 1:
The number 43 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 43

Going ahead to step 2:
91 divided by 43 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 86 from 91 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 43

Moving on to step 3:
When dividing 51 by 43, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 21.0
If we take 43 away from 51, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 43

Step 4:
The number 43 fits into 87 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
If we subtract 86 from 87, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 43

On to step 5:
The number 43 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 2120.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 43

Going ahead to step 6:
43 goes into 133 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 21203.0
The remainder is 4 after subtracting 129 from 133.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 43

Step 7:
43 can be fit into 46 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 212031.0
Subtracting 43 from 46 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 43

Let's proceed to step 8:
If we divide 36 by 43, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 2120310.0
Deduct 0 from 36 and we're left 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.

Going ahead to step 9:
360 divided by 43 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 2120310.8
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 43 fits into 160 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 2120310.83
If we take 129 away from 160, we end up 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.

Let's proceed to step 11:
If we divide 310 by 43, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2120310.837
If we take 301 away from 310, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
90 divided by 43 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2120310.8372
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
40 divided by 43 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2120310.8372
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 14:
The number 43 fits into 400 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2120310.837209
Deduct 387 from 400 and we're left with 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 15:
If we divide 130 by 43, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 2120310.8372093
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 16:
43 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2120310.8372093
Deduct 0 from 10 and we're left 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 2120310.8372093 with a remaining 1e-08.
