We divide 42288729 by 32
Our goal is to divide 42288729 by 32.

Moving on to step 1:
If we divide 4 by 32, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 32

Going ahead to step 2:
32 goes into 42 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 32 away from 42, we end up with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 32

On to step 3:
102 divided by 32 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 96 away from 102, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 32

Going ahead to step 4:
32 goes into 68 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtracting 64 from 68 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 32

On to step 5:
The number 32 fits into 48 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1321.0
Subtract 32 from 48 to get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 32

On to step 6:
The number 32 fits into 167 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 13215.0
Subtract 160 from 167 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 32

On to step 7:
32 can be fit into 72 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 132152.0
If we take 64 away from 72, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 32

On to step 8:
89 divided by 32 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 1321522.0
If we take 64 away from 89, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 32, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 1321522.7
If we take 224 away from 250, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
32 goes into 260 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1321522.78
Subtracting 256 from 260 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
When dividing 40 by 32, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1321522.781
Subtracting 32 from 40 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
32 goes into 80 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1321522.7812
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
The number 32 fits into 160 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1321522.78125
If we subtract 160 from 160, 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.

Advancing to step 14:
0 divided by 32 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1321522.78125
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.

On to step 15:
0 divided by 32 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1321522.78125
Deduct 0 from 0 and we're left 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 1321522.78125, with a leftover of 0.0.
