We look at the division of 66506637 by 213 
We want to figure out the number of times 66506637 can be divided by 213.

On to step 1:
If we divide 6 by 213, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 213

Let's proceed to step 2:
213 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 213

Advancing to step 3:
665 divided by 213 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 639 from 665 leaves us with 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 213

Step 4:
When dividing 260 by 213, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 47 after subtracting 213 from 260.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 213

On to step 5:
When dividing 476 by 213, we get 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 312.0
Subtract 426 from 476 to get 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 213

Moving on to step 6:
When dividing 506 by 213, we get 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 3122.0
Subtracting 426 from 506 leaves us with 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 213

Advancing to step 7:
213 goes into 803 3 times with a remainder of 164.
Use 3 as the next digit of our solution. 
Result so far: 31223.0
Subtracting 639 from 803 leaves us with 164.
Take the next digit (7) from the dividend and append it to 164, then repeat: 1647 / 213

Going ahead to step 8:
When dividing 1647 by 213, we get 7 with a remainder of 156.
Record the quotient 7 as the next digit in the result. 
Result so far: 312237.0
Deduct 1491 from 1647 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 9:
If we divide 1560 by 213, we get 7 and a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 312237.7
Subtracting 1491 from 1560 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
213 can be fit into 690 3 times, resulting in a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 312237.73
Subtracting 639 from 690 leaves us 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 11:
213 goes into 510 2 times with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 312237.732
If we take 426 away from 510, we end up 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 12:
213 can be fit into 840 3 times, resulting in a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 312237.7323
Subtract 639 from 840 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 13:
2010 divided by 213 is 9 with a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 312237.73239
Subtracting 1917 from 2010 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 14:
930 divided by 213 is 4 with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 312237.732394
Subtract 852 from 930 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 15:
If we divide 780 by 213, we get 3 and a remainder of 141.
Use 3 as the next digit of our solution. 
Result so far: 312237.7323943
The remainder is 141 after subtracting 639 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 16:
213 can be fit into 1410 6 times, resulting in a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 312237.73239436
If we take 1278 away from 1410, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

After the division, we end up with 312237.73239436 and a remainder of 1.32e-07.
