Let's divide 82590789 by 45
We're looking to find how many times 45 goes into 82590789.

Going ahead to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 45

On to step 2:
The number 45 fits into 82 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 82 to get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 45

Advancing to step 3:
The number 45 fits into 375 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 18.0
If we take 360 away from 375, we end up with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 45

Going ahead to step 4:
When dividing 159 by 45, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
The remainder is 24 after subtracting 135 from 159.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 45

Step 5:
The number 45 fits into 240 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1835.0
Deduct 225 from 240 and we're left with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 45

On to step 6:
When dividing 157 by 45, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 18353.0
The remainder is 22 after subtracting 135 from 157.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 45

Let's proceed to step 7:
When dividing 228 by 45, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 183535.0
The remainder is 3 after subtracting 225 from 228.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 45

Going ahead to step 8:
39 divided by 45 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 1835350.0
Subtracting 0 from 39 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
If we divide 390 by 45, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 1835350.8
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 45, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 1835350.86
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
45 goes into 300 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 1835350.866
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 1835350.866, with a leftover of 0.003.
