621173 ÷ 58 
We want to divide 621173 by 58.

Let's proceed to step 1:
If we divide 6 by 58, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 58

Let's proceed to step 2:
62 divided by 58 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 58 from 62 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 58

Going ahead to step 3:
If we divide 41 by 58, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 41, we end up with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 58

Step 4:
58 goes into 411 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 406 away from 411, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 58

Let's proceed to step 5:
57 divided by 58 is 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 1070.0
If we subtract 0 from 57, we get 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 58

Advancing to step 6:
58 can be fit into 573 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 10709.0
Deduct 522 from 573 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
58 can be fit into 510 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 10709.8
Subtract 464 from 510 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
If we divide 460 by 58, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 10709.87
If we subtract 406 from 460, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
The number 58 fits into 540 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 10709.879
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
180 divided by 58 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 10709.8793
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
58 goes into 60 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 10709.87931
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
When dividing 20 by 58, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10709.87931
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
200 divided by 58 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 10709.8793103
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
If we divide 260 by 58, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 10709.87931034
If we take 232 away from 260, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 10709.87931034, with a leftover of 2.8e-08.
