We're dividing 34645530 by 812 
We want to divide 34645530 by 812.

Step 1:
812 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 812

Moving on to step 2:
812 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 812

Advancing to step 3:
If we divide 346 by 812, we get 0 and a remainder of 346.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 346 leaves us with 346.
Include the next digit (4) from the dividend after 346, then repeat: 3464 / 812

On to step 4:
812 can be fit into 3464 4 times, resulting in a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3248 from 3464, we get 216.
Include the next digit (5) from the dividend after 216, then repeat: 2165 / 812

Going ahead to step 5:
When dividing 2165 by 812, we get 2 with a remainder of 541.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 541 after subtracting 1624 from 2165.
Bring next digit (5) of the dividend behind the 541 and repeat the process: 5415 / 812

Advancing to step 6:
If we divide 5415 by 812, we get 6 and a remainder of 543.
Use 6 as the next digit of our solution. 
Result so far: 426.0
Subtracting 4872 from 5415 leaves us with 543.
Append the next digit (3) from the dividend to 543 and continue with: 5433 / 812

Let's proceed to step 7:
If we divide 5433 by 812, we get 6 and a remainder of 561.
Put 6 as the next digit of the answer. 
Result so far: 4266.0
Deduct 4872 from 5433 and we're left with 561.
Include the next digit (0) from the dividend after 561, then repeat: 5610 / 812

Going ahead to step 8:
When dividing 5610 by 812, we get 6 with a remainder of 738.
Write down 6 as next digit of the result. 
Result so far: 42666.0
If we take 4872 away from 5610, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 9:
7380 divided by 812 is 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 42666.9
Subtract 7308 from 7380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
812 can be fit into 720 0 times, resulting in a remainder of 720.
The number 0 becomes the next digit in our result. 
Result so far: 42666.9
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 11:
If we divide 7200 by 812, we get 8 and a remainder of 704.
Put 8 as the next digit of the answer. 
Result so far: 42666.908
If we take 6496 away from 7200, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 12:
812 goes into 7040 8 times with a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 42666.9088
Subtracting 6496 from 7040 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final outcome is 42666.9088, with a leftover of 0.00544.
