We're dividing 43530559 by 665 
Let's see how many times 665 fits into 43530559.

Advancing to step 1:
665 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 665

On to step 2:
665 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 665

Let's proceed to step 3:
When dividing 435 by 665, we get 0 with a remainder of 435.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 435 after subtracting 0 from 435.
Grab the next digit (3) from the dividend, add it to 435, then carry on: 4353 / 665

Let's proceed to step 4:
When dividing 4353 by 665, we get 6 with a remainder of 363.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 3990 from 4353 and we're left with 363.
Bring next digit (0) of the dividend behind the 363 and repeat the process: 3630 / 665

Advancing to step 5:
665 can be fit into 3630 5 times, resulting in a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtracting 3325 from 3630 leaves us with 305.
Bring next digit (5) of the dividend behind the 305 and repeat the process: 3055 / 665

Going ahead to step 6:
The number 665 fits into 3055 4 times, leaving a remainder of 395.
Put 4 as the next digit of the answer. 
Result so far: 654.0
The remainder is 395 after subtracting 2660 from 3055.
Grab the next digit (5) from the dividend, add it to 395, then carry on: 3955 / 665

Let's proceed to step 7:
The number 665 fits into 3955 5 times, leaving a remainder of 630.
Record the quotient 5 as the next digit in the result. 
Result so far: 6545.0
If we take 3325 away from 3955, we end up with 630.
Bring next digit (9) of the dividend behind the 630 and repeat the process: 6309 / 665

Moving on to step 8:
The number 665 fits into 6309 9 times, leaving a remainder of 324.
Put 9 as the next digit of the answer. 
Result so far: 65459.0
Subtracting 5985 from 6309 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 9:
If we divide 3240 by 665, we get 4 and a remainder of 580.
The number 4 becomes the next digit in our result. 
Result so far: 65459.4
Deduct 2660 from 3240 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 10:
The number 665 fits into 5800 8 times, leaving a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 65459.48
Deduct 5320 from 5800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 11:
If we divide 4800 by 665, we get 7 and a remainder of 145.
Record the quotient 7 as the next digit in the result. 
Result so far: 65459.487
If we take 4655 away from 4800, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 12:
1450 divided by 665 is 2 with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 65459.4872
The remainder is 120 after subtracting 1330 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
When dividing 1200 by 665, we get 1 with a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 65459.48721
The remainder is 535 after subtracting 665 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 14:
If we divide 5350 by 665, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 65459.487218
The remainder is 30 after subtracting 5320 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
665 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 65459.487218
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 16:
665 goes into 3000 4 times with a remainder of 340.
The number 4 becomes the next digit in our result. 
Result so far: 65459.48721804
If we subtract 2660 from 3000, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Our division results in 65459.48721804 with a remaining 3.4e-07.
