We're dividing 37020863 by 45 
We want to divide 37020863 by 45.

Advancing to step 1:
3 divided by 45 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 45

Advancing to step 2:
The number 45 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 45

Let's proceed to step 3:
45 can be fit into 370 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 10 after subtracting 360 from 370.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 45

Step 4:
If we divide 102 by 45, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 90 from 102 and we're left with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 45

Advancing to step 5:
When dividing 120 by 45, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 822.0
The remainder is 30 after subtracting 90 from 120.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 45

On to step 6:
When dividing 308 by 45, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 8226.0
The remainder is 38 after subtracting 270 from 308.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 45

Let's proceed to step 7:
When dividing 386 by 45, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 82268.0
Subtracting 360 from 386 leaves us with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 45

Let's proceed to step 8:
45 goes into 263 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 822685.0
If we take 225 away from 263, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
45 goes into 380 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 822685.8
If we subtract 360 from 380, we get 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 10:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 822685.84
Subtract 180 from 200 to get 20.
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 11:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 822685.844
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 822685.844, with a leftover of 0.002.
