We're dividing 86153534 by 4 
We want to figure out the number of times 86153534 can be divided by 4.

Step 1:
4 goes into 8 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 4

Moving on to step 2:
4 goes into 6 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 4 from 6 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 4

On to step 3:
4 goes into 21 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 215.0
If we subtract 20 from 21, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 4

Going ahead to step 4:
If we divide 15 by 4, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 2153.0
If we take 12 away from 15, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

Step 5:
4 can be fit into 33 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 21538.0
If we take 32 away from 33, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

Moving on to step 6:
15 divided by 4 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 215383.0
Deduct 12 from 15 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

Step 7:
33 divided by 4 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 2153838.0
The remainder is 1 after subtracting 32 from 33.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

Going ahead to step 8:
When dividing 14 by 4, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 21538383.0
If we take 12 away from 14, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 21538383.5
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21538383.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21538383.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 21538383.5 with a remainder of 0.0.
