64156326 ÷ 40 
We're looking to find how many times 40 goes into 64156326.

Step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 40

Step 2:
40 goes into 64 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 40 from 64, we get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 40

Let's proceed to step 3:
The number 40 fits into 241 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 240 from 241 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 40

Going ahead to step 4:
15 divided by 40 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 160.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 40

Moving on to step 5:
The number 40 fits into 156 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 1603.0
If we take 120 away from 156, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 40

Advancing to step 6:
40 goes into 363 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 16039.0
If we subtract 360 from 363, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 40

Step 7:
32 divided by 40 is 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 160390.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 40

Let's proceed to step 8:
40 goes into 326 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 1603908.0
If we subtract 320 from 326, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
40 goes into 60 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1603908.1
The remainder is 20 after subtracting 40 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1603908.15
If we take 200 away from 200, 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.

Advancing to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1603908.15
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.

Let's proceed to step 12:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1603908.15
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 1603908.15 with a remainder of 0.0.
