Let's divide 53458631 by 586
Let's see how many times 586 fits into 53458631.

Advancing to step 1:
5 divided by 586 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 586

Going ahead to step 2:
53 divided by 586 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 586

On to step 3:
The number 586 fits into 534 0 times, leaving a remainder of 534.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Bring next digit (5) of the dividend behind the 534 and repeat the process: 5345 / 586

On to step 4:
586 goes into 5345 9 times with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 5274 away from 5345, we end up with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 586

Let's proceed to step 5:
The number 586 fits into 718 1 times, leaving a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Deduct 586 from 718 and we're left with 132.
Grab the next digit (6) from the dividend, add it to 132, then carry on: 1326 / 586

Advancing to step 6:
When dividing 1326 by 586, we get 2 with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 912.0
Subtract 1172 from 1326 to get 154.
Include the next digit (3) from the dividend after 154, then repeat: 1543 / 586

Advancing to step 7:
When dividing 1543 by 586, we get 2 with a remainder of 371.
Put 2 as the next digit of the answer. 
Result so far: 9122.0
Deduct 1172 from 1543 and we're left with 371.
Include the next digit (1) from the dividend after 371, then repeat: 3711 / 586

Step 8:
586 goes into 3711 6 times with a remainder of 195.
The number 6 becomes the next digit in our result. 
Result so far: 91226.0
Deduct 3516 from 3711 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 9:
If we divide 1950 by 586, we get 3 and a remainder of 192.
Record the quotient 3 as the next digit in the result. 
Result so far: 91226.3
Subtract 1758 from 1950 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 10:
1920 divided by 586 is 3 with a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 91226.33
If we subtract 1758 from 1920, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

After the division, we end up with 91226.33 and a remainder of 0.162.
