Let's divide 12574485 by 812
Our goal is to divide 12574485 by 812.

Step 1:
1 divided by 812 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 812

Going ahead to step 2:
The number 812 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 812

Going ahead to step 3:
When dividing 125 by 812, we get 0 with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 812

Advancing to step 4:
1257 divided by 812 is 1 with a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 812 from 1257 leaves us with 445.
Include the next digit (4) from the dividend after 445, then repeat: 4454 / 812

Let's proceed to step 5:
4454 divided by 812 is 5 with a remainder of 394.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 4060 from 4454 and we're left with 394.
Bring next digit (4) of the dividend behind the 394 and repeat the process: 3944 / 812

On to step 6:
812 can be fit into 3944 4 times, resulting in a remainder of 696.
The next digit of our result is 4. 
Result so far: 154.0
If we subtract 3248 from 3944, we get 696.
Append the next digit (8) from the dividend to 696 and continue with: 6968 / 812

Step 7:
The number 812 fits into 6968 8 times, leaving a remainder of 472.
The next digit of our result is 8. 
Result so far: 1548.0
Deduct 6496 from 6968 and we're left with 472.
Include the next digit (5) from the dividend after 472, then repeat: 4725 / 812

Advancing to step 8:
4725 divided by 812 is 5 with a remainder of 665.
Write down 5 as next digit of the result. 
Result so far: 15485.0
If we take 4060 away from 4725, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 9:
812 can be fit into 6650 8 times, resulting in a remainder of 154.
The next digit of our result is 8. 
Result so far: 15485.8
Deduct 6496 from 6650 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
1540 divided by 812 is 1 with a remainder of 728.
Write down 1 as next digit of the result. 
Result so far: 15485.81
If we take 812 away from 1540, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 11:
When dividing 7280 by 812, we get 8 with a remainder of 784.
The number 8 becomes the next digit in our result. 
Result so far: 15485.818
Subtracting 6496 from 7280 leaves us with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 12:
812 goes into 7840 9 times with a remainder of 532.
Put 9 as the next digit of the answer. 
Result so far: 15485.8189
Deduct 7308 from 7840 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 13:
The number 812 fits into 5320 6 times, leaving a remainder of 448.
Use 6 as the next digit of our solution. 
Result so far: 15485.81896
Deduct 4872 from 5320 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 14:
When dividing 4480 by 812, we get 5 with a remainder of 420.
The number 5 becomes the next digit in our result. 
Result so far: 15485.818965
Subtract 4060 from 4480 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
If we divide 4200 by 812, we get 5 and a remainder of 140.
The next digit of our result is 5. 
Result so far: 15485.8189655
The remainder is 140 after subtracting 4060 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 15485.8189655 with a remaining 1.4e-06.
