Let's divide 18945590 by 43
We want to figure out the number of times 18945590 can be divided by 43.

Let's proceed to step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 43

Let's proceed to step 2:
If we divide 18 by 43, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 43

Going ahead to step 3:
43 goes into 189 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 172 from 189 to get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 43

Let's proceed to step 4:
If we divide 174 by 43, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 172 from 174 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 43

Step 5:
43 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 440.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 43

Step 6:
The number 43 fits into 255 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 4405.0
If we take 215 away from 255, we end up with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 43

Advancing to step 7:
43 goes into 409 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 44059.0
If we take 387 away from 409, we end up with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 43

Going ahead to step 8:
220 divided by 43 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 440595.0
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 43, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 440595.1
Subtracting 43 from 50 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
When dividing 70 by 43, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 440595.11
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 440595.11 and a remainder of 0.027.
