We look at the division of 645621 by 58 
Let's see how many times 58 fits into 645621.

Moving on to step 1:
When dividing 6 by 58, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 58

Let's proceed to step 2:
The number 58 fits into 64 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 58 from 64 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 58

Step 3:
If we divide 65 by 58, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 58 away from 65, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 58

Going ahead to step 4:
58 goes into 76 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 111.0
Subtracting 58 from 76 leaves us with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 58

Let's proceed to step 5:
The number 58 fits into 182 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 1113.0
If we take 174 away from 182, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 58

Advancing to step 6:
The number 58 fits into 81 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 11131.0
If we take 58 away from 81, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
The number 58 fits into 230 3 times, leaving a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 11131.3
Subtracting 174 from 230 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
If we divide 560 by 58, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 11131.39
Deduct 522 from 560 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
58 goes into 380 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11131.396
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
If we divide 320 by 58, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 11131.3965
Subtracting 290 from 320 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 58, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11131.39655
The remainder is 10 after subtracting 290 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 11131.39655 with a remaining 1e-05.
