64216902 ÷ 713 
We want to figure out the number of times 64216902 can be divided by 713.

On to step 1:
When dividing 6 by 713, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 713

Going ahead to step 2:
713 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 713

Going ahead to step 3:
713 goes into 642 0 times with a remainder of 642.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Take the next digit (1) from the dividend and append it to 642, then repeat: 6421 / 713

On to step 4:
The number 713 fits into 6421 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 6417 away from 6421, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 713

Step 5:
If we divide 46 by 713, we get 0 and a remainder of 46.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 46 and we're left with 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 713

Let's proceed to step 6:
When dividing 469 by 713, we get 0 with a remainder of 469.
Put 0 as the next digit of the answer. 
Result so far: 900.0
Deduct 0 from 469 and we're left with 469.
Bring next digit (0) of the dividend behind the 469 and repeat the process: 4690 / 713

On to step 7:
4690 divided by 713 is 6 with a remainder of 412.
Record the quotient 6 as the next digit in the result. 
Result so far: 9006.0
The remainder is 412 after subtracting 4278 from 4690.
Include the next digit (2) from the dividend after 412, then repeat: 4122 / 713

Let's proceed to step 8:
When dividing 4122 by 713, we get 5 with a remainder of 557.
Put 5 as the next digit of the answer. 
Result so far: 90065.0
If we subtract 3565 from 4122, we get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Step 9:
713 can be fit into 5570 7 times, resulting in a remainder of 579.
Record the quotient 7 as the next digit in the result. 
Result so far: 90065.7
Deduct 4991 from 5570 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Let's proceed to step 10:
713 can be fit into 5790 8 times, resulting in a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 90065.78
Subtract 5704 from 5790 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
713 can be fit into 860 1 times, resulting in a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 90065.781
Subtracting 713 from 860 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 12:
If we divide 1470 by 713, we get 2 and a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 90065.7812
Subtract 1426 from 1470 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
The number 713 fits into 440 0 times, leaving a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 90065.7812
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 14:
4400 divided by 713 is 6 with a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 90065.781206
Deduct 4278 from 4400 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 15:
If we divide 1220 by 713, we get 1 and a remainder of 507.
Put 1 as the next digit of the answer. 
Result so far: 90065.7812061
If we subtract 713 from 1220, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 16:
713 goes into 5070 7 times with a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 90065.78120617
Deduct 4991 from 5070 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 90065.78120617 with a balance of 7.9e-08.
