We look at the division of 53621307 by 258 
Let's see how many times 258 fits into 53621307.

Moving on to step 1:
5 divided by 258 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 258

Let's proceed to step 2:
If we divide 53 by 258, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 258

Moving on to step 3:
258 can be fit into 536 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 516 from 536, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 258

Let's proceed to step 4:
258 can be fit into 202 0 times, resulting in a remainder of 202.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 202, we get 202.
Grab the next digit (1) from the dividend, add it to 202, then carry on: 2021 / 258

Moving on to step 5:
2021 divided by 258 is 7 with a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 207.0
If we subtract 1806 from 2021, we get 215.
Append the next digit (3) from the dividend to 215 and continue with: 2153 / 258

Going ahead to step 6:
258 goes into 2153 8 times with a remainder of 89.
The number 8 becomes the next digit in our result. 
Result so far: 2078.0
Subtracting 2064 from 2153 leaves us with 89.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 258

On to step 7:
When dividing 890 by 258, we get 3 with a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 20783.0
The remainder is 116 after subtracting 774 from 890.
Grab the next digit (7) from the dividend, add it to 116, then carry on: 1167 / 258

Let's proceed to step 8:
If we divide 1167 by 258, we get 4 and a remainder of 135.
Use 4 as the next digit of our solution. 
Result so far: 207834.0
If we subtract 1032 from 1167, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
The number 258 fits into 1350 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 207834.5
Subtract 1290 from 1350 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 258, we get 2 with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 207834.52
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
840 divided by 258 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 207834.523
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
The number 258 fits into 660 2 times, leaving a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 207834.5232
Subtracting 516 from 660 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
258 can be fit into 1440 5 times, resulting in a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 207834.52325
If we subtract 1290 from 1440, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
258 goes into 1500 5 times with a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 207834.523255
The remainder is 210 after subtracting 1290 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The quotient of the division is 207834.523255, and the remainder is 2.1e-05.
