We look at the division of 43206550 by 86 
We want to figure out the number of times 43206550 can be divided by 86.

Advancing to step 1:
86 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 86

Advancing to step 2:
43 divided by 86 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 86

Step 3:
432 divided by 86 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 430 from 432 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 86

Step 4:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 86

Step 5:
206 divided by 86 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 502.0
Subtract 172 from 206 to get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 86

Let's proceed to step 6:
86 can be fit into 345 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 5024.0
If we subtract 344 from 345, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 86

Moving on to step 7:
15 divided by 86 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 50240.0
If we take 0 away from 15, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 86

Let's proceed to step 8:
When dividing 150 by 86, we get 1 with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 502401.0
Deduct 86 from 150 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 502401.7
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
380 divided by 86 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 502401.74
If we take 344 away from 380, we end up 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.

On to step 11:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 502401.744
Deduct 344 from 360 and we're left 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.

Our division results in 502401.744 with a remaining 0.0016.
