658902 divided by 40 
Our goal is to divide 658902 by 40.

Going ahead to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 40

Going ahead to step 2:
40 goes into 65 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 25 after subtracting 40 from 65.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 40

On to step 3:
258 divided by 40 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 240 from 258 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 40

On to step 4:
The number 40 fits into 189 4 times, leaving a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtract 160 from 189 to get 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 40

Advancing to step 5:
40 can be fit into 290 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1647.0
Deduct 280 from 290 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 40

Going ahead to step 6:
When dividing 102 by 40, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 16472.0
If we take 80 away from 102, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
The number 40 fits into 220 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 16472.5
Deduct 200 from 220 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16472.55
Deduct 200 from 200 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.

Our division results in 16472.55 with a remaining 0.0.
