We divide 85353958 by 40
Let's see how many times 40 fits into 85353958.

Going ahead to step 1:
When dividing 8 by 40, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 40

Going ahead to step 2:
40 can be fit into 85 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 80 from 85 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 40

On to step 3:
If we divide 53 by 40, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 21.0
If we take 40 away from 53, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 40

Let's proceed to step 4:
When dividing 135 by 40, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 213.0
Subtract 120 from 135 to get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 40

Step 5:
When dividing 153 by 40, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 2133.0
The remainder is 33 after subtracting 120 from 153.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 40

Moving on to step 6:
40 can be fit into 339 8 times, resulting in a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 21338.0
If we take 320 away from 339, we end up with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 40

On to step 7:
40 can be fit into 195 4 times, resulting in a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 213384.0
If we subtract 160 from 195, we get 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 40

On to step 8:
358 divided by 40 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 2133848.0
If we subtract 320 from 358, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
380 divided by 40 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 2133848.9
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 40, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2133848.95
The remainder is 0 after subtracting 200 from 200.
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 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2133848.95
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.

Going ahead to step 12:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2133848.95
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.

After the division, we end up with 2133848.95 and a remainder of 0.0.
