We look at the division of 43521386 by 27 
We want to figure out the number of times 43521386 can be divided by 27.

Let's proceed to step 1:
When dividing 4 by 27, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 27

Advancing to step 2:
43 divided by 27 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 27 away from 43, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 27

Advancing to step 3:
When dividing 165 by 27, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 162 from 165, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 27

Moving on to step 4:
27 goes into 32 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we subtract 27 from 32, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 27

Advancing to step 5:
If we divide 51 by 27, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1611.0
Subtracting 27 from 51 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 27

Advancing to step 6:
27 can be fit into 243 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 16119.0
Subtract 243 from 243 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 27

Moving on to step 7:
If we divide 8 by 27, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 161190.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 27

Going ahead to step 8:
If we divide 86 by 27, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 1611903.0
If we take 81 away from 86, we end up with 5.
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:
The number 27 fits into 50 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1611903.1
Subtract 27 from 50 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
230 divided by 27 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 1611903.18
Subtracting 216 from 230 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
When dividing 140 by 27, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1611903.185
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 27, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1611903.1851
Subtracting 27 from 50 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
When dividing 230 by 27, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 1611903.18518
If we subtract 216 from 230, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
140 divided by 27 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1611903.185185
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 15:
When dividing 50 by 27, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1611903.1851851
The remainder is 23 after subtracting 27 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 16:
27 can be fit into 230 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 1611903.18518518
If we take 216 away from 230, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 1611903.18518518 with a remaining 1.4e-08.
