We look at the division of 58473645 by 820 
Let's see how many times 820 fits into 58473645.

Let's proceed to step 1:
820 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 820

Let's proceed to step 2:
820 can be fit into 58 0 times, resulting in a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 820

Advancing to step 3:
If we divide 584 by 820, we get 0 and a remainder of 584.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 584 leaves us with 584.
Fetch the next digit (7) from the dividend, attach it to 584 and continue: 5847 / 820

On to step 4:
When dividing 5847 by 820, we get 7 with a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5740 from 5847 to get 107.
Bring next digit (3) of the dividend behind the 107 and repeat the process: 1073 / 820

Advancing to step 5:
When dividing 1073 by 820, we get 1 with a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 820 from 1073 leaves us with 253.
Append the next digit (6) from the dividend to 253 and continue with: 2536 / 820

Going ahead to step 6:
If we divide 2536 by 820, we get 3 and a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 713.0
If we take 2460 away from 2536, we end up with 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 820

Going ahead to step 7:
820 goes into 764 0 times with a remainder of 764.
The next digit of our result is 0. 
Result so far: 7130.0
If we subtract 0 from 764, we get 764.
Include the next digit (5) from the dividend after 764, then repeat: 7645 / 820

Advancing to step 8:
The number 820 fits into 7645 9 times, leaving a remainder of 265.
The next digit of our result is 9. 
Result so far: 71309.0
Subtract 7380 from 7645 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
The number 820 fits into 2650 3 times, leaving a remainder of 190.
Use 3 as the next digit of our solution. 
Result so far: 71309.3
If we take 2460 away from 2650, we end up 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.

Step 10:
If we divide 1900 by 820, we get 2 and a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 71309.32
If we take 1640 away from 1900, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
820 goes into 2600 3 times with a remainder of 140.
The next digit of our result is 3. 
Result so far: 71309.323
Subtract 2460 from 2600 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
820 goes into 1400 1 times with a remainder of 580.
Record the quotient 1 as the next digit in the result. 
Result so far: 71309.3231
Subtracting 820 from 1400 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 13:
When dividing 5800 by 820, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 71309.32317
The remainder is 60 after subtracting 5740 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
When dividing 600 by 820, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 71309.32317
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 15:
820 can be fit into 6000 7 times, resulting in a remainder of 260.
Use 7 as the next digit of our solution. 
Result so far: 71309.3231707
Deduct 5740 from 6000 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
If we divide 2600 by 820, we get 3 and a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 71309.32317073
If we subtract 2460 from 2600, we get 140.
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 71309.32317073 with a remaining 1.4e-07.
