We look at the division of 40457803 by 85 
We want to divide 40457803 by 85.

Advancing to step 1:
4 divided by 85 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 85

Going ahead to step 2:
The number 85 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 85

On to step 3:
85 can be fit into 404 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 340 from 404 to get 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 85

Let's proceed to step 4:
The number 85 fits into 645 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 595 from 645, we get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 85

Step 5:
507 divided by 85 is 5 with a remainder of 82.
Use 5 as the next digit of our solution. 
Result so far: 475.0
Subtract 425 from 507 to get 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 85

Let's proceed to step 6:
The number 85 fits into 828 9 times, leaving a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 4759.0
The remainder is 63 after subtracting 765 from 828.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 85

Going ahead to step 7:
If we divide 630 by 85, we get 7 and a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 47597.0
The remainder is 35 after subtracting 595 from 630.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 85

Advancing to step 8:
The number 85 fits into 353 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 475974.0
If we take 340 away from 353, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
The number 85 fits into 130 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 475974.1
If we subtract 85 from 130, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
If we divide 450 by 85, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 475974.15
Deduct 425 from 450 and we're left 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.

Advancing to step 11:
The number 85 fits into 250 2 times, leaving a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 475974.152
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
85 can be fit into 800 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 475974.1529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
85 goes into 350 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 475974.15294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 85 fits into 100 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 475974.152941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 475974.1529411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 475974.1529411 with a remaining 6.5e-07.
