31609485 ÷ 445 
We want to divide 31609485 by 445.

Step 1:
If we divide 3 by 445, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 445

Advancing to step 2:
The number 445 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 445

Going ahead to step 3:
445 can be fit into 316 0 times, resulting in a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Take the next digit (0) from the dividend and append it to 316, then repeat: 3160 / 445

Step 4:
If we divide 3160 by 445, we get 7 and a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 3115 from 3160 leaves us with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 445

Advancing to step 5:
If we divide 459 by 445, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 445 from 459, we get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 445

Step 6:
If we divide 144 by 445, we get 0 and a remainder of 144.
Write down 0 as next digit of the result. 
Result so far: 710.0
If we take 0 away from 144, we end up with 144.
Include the next digit (8) from the dividend after 144, then repeat: 1448 / 445

Step 7:
1448 divided by 445 is 3 with a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 7103.0
If we take 1335 away from 1448, we end up with 113.
Bring next digit (5) of the dividend behind the 113 and repeat the process: 1135 / 445

On to step 8:
If we divide 1135 by 445, we get 2 and a remainder of 245.
The number 2 becomes the next digit in our result. 
Result so far: 71032.0
Subtract 890 from 1135 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 9:
The number 445 fits into 2450 5 times, leaving a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 71032.5
If we subtract 2225 from 2450, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 10:
445 can be fit into 2250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 71032.55
If we take 2225 away from 2250, we end up 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.

Our division results in 71032.55 with a remaining 0.025.
