We look at the division of 646487 by 58 
We're looking to find how many times 58 goes into 646487.

Step 1:
If we divide 6 by 58, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 58

Step 2:
When dividing 64 by 58, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 58 from 64, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 58

On to step 3:
The number 58 fits into 66 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 58 from 66, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 58

Advancing to step 4:
If we divide 84 by 58, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 111.0
If we subtract 58 from 84, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 58

On to step 5:
58 can be fit into 268 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1114.0
The remainder is 36 after subtracting 232 from 268.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 58

On to step 6:
If we divide 367 by 58, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 11146.0
Subtract 348 from 367 to get 19.
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 7:
58 goes into 190 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 11146.3
Deduct 174 from 190 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
58 can be fit into 160 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 11146.32
If we subtract 116 from 160, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
58 can be fit into 440 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 11146.327
If we take 406 away from 440, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 58 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11146.3275
The remainder is 50 after subtracting 290 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
When dividing 500 by 58, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 11146.32758
If we subtract 464 from 500, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
The number 58 fits into 360 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 11146.327586
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
If we divide 120 by 58, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 11146.3275862
The remainder is 4 after subtracting 116 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
58 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11146.3275862
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 11146.3275862 with a remaining 4e-08.
