We divide 86636190 by 48
We want to figure out the number of times 86636190 can be divided by 48.

Step 1:
If we divide 8 by 48, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 48

On to step 2:
48 goes into 86 1 times with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 48 from 86 leaves us with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 48

Going ahead to step 3:
48 can be fit into 386 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 384 from 386, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 48

On to step 4:
48 goes into 23 0 times with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 180.0
If we subtract 0 from 23, we get 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 48

Advancing to step 5:
48 can be fit into 236 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 1804.0
The remainder is 44 after subtracting 192 from 236.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 48

Moving on to step 6:
48 can be fit into 441 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 18049.0
If we take 432 away from 441, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 48

Let's proceed to step 7:
99 divided by 48 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 180492.0
If we subtract 96 from 99, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 48

Going ahead to step 8:
30 divided by 48 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1804920.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
48 goes into 300 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 1804920.6
If we take 288 away from 300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 48, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1804920.62
Deduct 96 from 120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
240 divided by 48 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1804920.625
Subtract 240 from 240 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 12:
48 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1804920.625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
48 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1804920.625
If we take 0 away from 0, we end up with 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 outcome is 1804920.625, with a leftover of 0.0.
