We're dividing 86391243 by 536 
Our goal is to divide 86391243 by 536.

Advancing to step 1:
The number 536 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 536

On to step 2:
When dividing 86 by 536, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 536

On to step 3:
536 goes into 863 1 times with a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 327 after subtracting 536 from 863.
Take the next digit (9) from the dividend and append it to 327, then repeat: 3279 / 536

Step 4:
If we divide 3279 by 536, we get 6 and a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 63 after subtracting 3216 from 3279.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 536

Moving on to step 5:
536 goes into 631 1 times with a remainder of 95.
The next digit of our result is 1. 
Result so far: 161.0
If we subtract 536 from 631, we get 95.
Append the next digit (2) from the dividend to 95 and continue with: 952 / 536

On to step 6:
If we divide 952 by 536, we get 1 and a remainder of 416.
Write down 1 as next digit of the result. 
Result so far: 1611.0
Deduct 536 from 952 and we're left with 416.
Bring next digit (4) of the dividend behind the 416 and repeat the process: 4164 / 536

Step 7:
If we divide 4164 by 536, we get 7 and a remainder of 412.
Use 7 as the next digit of our solution. 
Result so far: 16117.0
Deduct 3752 from 4164 and we're left with 412.
Fetch the next digit (3) from the dividend, attach it to 412 and continue: 4123 / 536

Let's proceed to step 8:
When dividing 4123 by 536, we get 7 with a remainder of 371.
Record the quotient 7 as the next digit in the result. 
Result so far: 161177.0
Subtract 3752 from 4123 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 9:
If we divide 3710 by 536, we get 6 and a remainder of 494.
The next digit of our result is 6. 
Result so far: 161177.6
Subtracting 3216 from 3710 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 10:
The number 536 fits into 4940 9 times, leaving a remainder of 116.
The number 9 becomes the next digit in our result. 
Result so far: 161177.69
Subtract 4824 from 4940 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 11:
When dividing 1160 by 536, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 161177.692
Subtracting 1072 from 1160 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
The number 536 fits into 880 1 times, leaving a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 161177.6921
If we take 536 away from 880, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 13:
When dividing 3440 by 536, we get 6 with a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 161177.69216
Subtracting 3216 from 3440 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 14:
If we divide 2240 by 536, we get 4 and a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 161177.692164
If we take 2144 away from 2240, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
536 goes into 960 1 times with a remainder of 424.
The number 1 becomes the next digit in our result. 
Result so far: 161177.6921641
The remainder is 424 after subtracting 536 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 16:
The number 536 fits into 4240 7 times, leaving a remainder of 488.
Put 7 as the next digit of the answer. 
Result so far: 161177.69216417
If we take 3752 away from 4240, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

After the division, we end up with 161177.69216417 and a remainder of 4.88e-07.
