Let's divide 58600645 by 809
We want to divide 58600645 by 809.

Advancing to step 1:
809 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 809

Moving on to step 2:
58 divided by 809 is 0 with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 809

On to step 3:
809 goes into 586 0 times with a remainder of 586.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 586 to get 586.
Append the next digit (0) from the dividend to 586 and continue with: 5860 / 809

Step 4:
809 can be fit into 5860 7 times, resulting in a remainder of 197.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 5663 from 5860 leaves us with 197.
Grab the next digit (0) from the dividend, add it to 197, then carry on: 1970 / 809

On to step 5:
1970 divided by 809 is 2 with a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 1618 from 1970, we get 352.
Bring next digit (6) of the dividend behind the 352 and repeat the process: 3526 / 809

Advancing to step 6:
The number 809 fits into 3526 4 times, leaving a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 724.0
If we take 3236 away from 3526, we end up with 290.
Fetch the next digit (4) from the dividend, attach it to 290 and continue: 2904 / 809

Moving on to step 7:
809 goes into 2904 3 times with a remainder of 477.
The next digit of our result is 3. 
Result so far: 7243.0
Subtracting 2427 from 2904 leaves us with 477.
Grab the next digit (5) from the dividend, add it to 477, then carry on: 4775 / 809

Step 8:
809 can be fit into 4775 5 times, resulting in a remainder of 730.
Record the quotient 5 as the next digit in the result. 
Result so far: 72435.0
Subtracting 4045 from 4775 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 9:
7300 divided by 809 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 72435.9
The remainder is 19 after subtracting 7281 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
809 can be fit into 190 0 times, resulting in a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 72435.9
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
1900 divided by 809 is 2 with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 72435.902
If we take 1618 away from 1900, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 12:
809 goes into 2820 3 times with a remainder of 393.
Record the quotient 3 as the next digit in the result. 
Result so far: 72435.9023
If we take 2427 away from 2820, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 13:
If we divide 3930 by 809, we get 4 and a remainder of 694.
Use 4 as the next digit of our solution. 
Result so far: 72435.90234
If we take 3236 away from 3930, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 14:
809 goes into 6940 8 times with a remainder of 468.
Write down 8 as next digit of the result. 
Result so far: 72435.902348
Deduct 6472 from 6940 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 15:
809 can be fit into 4680 5 times, resulting in a remainder of 635.
Record the quotient 5 as the next digit in the result. 
Result so far: 72435.9023485
Subtracting 4045 from 4680 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 16:
The number 809 fits into 6350 7 times, leaving a remainder of 687.
Put 7 as the next digit of the answer. 
Result so far: 72435.90234857
If we take 5663 away from 6350, we end up with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

After the division, we end up with 72435.90234857 and a remainder of 6.87e-07.
