We're dividing 52586736 by 210 
We're looking to find how many times 210 goes into 52586736.

Step 1:
When dividing 5 by 210, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 210

Advancing to step 2:
210 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 210

On to step 3:
The number 210 fits into 525 2 times, leaving a remainder of 105.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 420 away from 525, we end up with 105.
Bring next digit (8) of the dividend behind the 105 and repeat the process: 1058 / 210

Going ahead to step 4:
1058 divided by 210 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 1050 from 1058 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 210

Going ahead to step 5:
210 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 250.0
Subtract 0 from 86 to get 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 210

Step 6:
210 can be fit into 867 4 times, resulting in a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 2504.0
Subtracting 840 from 867 leaves us with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 210

Let's proceed to step 7:
210 can be fit into 273 1 times, resulting in a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 25041.0
Subtract 210 from 273 to get 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 210

Let's proceed to step 8:
210 goes into 636 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 250413.0
Subtract 630 from 636 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
The number 210 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 250413.0
Subtract 0 from 60 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.

Step 10:
210 can be fit into 600 2 times, resulting in a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 250413.02
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
When dividing 1800 by 210, we get 8 with a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 250413.028
The remainder is 120 after subtracting 1680 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
210 goes into 1200 5 times with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 250413.0285
If we subtract 1050 from 1200, 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.

Moving on to step 13:
210 goes into 1500 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 250413.02857
Subtracting 1470 from 1500 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 14:
When dividing 300 by 210, we get 1 with a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 250413.028571
Subtract 210 from 300 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
210 goes into 900 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 250413.0285714
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
The number 210 fits into 600 2 times, leaving a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 250413.02857142
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 250413.02857142 with a remainder of 1.8e-07.
