64210875 ÷ 902 
We want to figure out the number of times 64210875 can be divided by 902.

Let's proceed to step 1:
The number 902 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 902

Advancing to step 2:
902 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 902

Going ahead to step 3:
902 can be fit into 642 0 times, resulting in a remainder of 642.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 642, we end up with 642.
Append the next digit (1) from the dividend to 642 and continue with: 6421 / 902

Going ahead to step 4:
902 can be fit into 6421 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 107 after subtracting 6314 from 6421.
Grab the next digit (0) from the dividend, add it to 107, then carry on: 1070 / 902

On to step 5:
902 goes into 1070 1 times with a remainder of 168.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Deduct 902 from 1070 and we're left with 168.
Grab the next digit (8) from the dividend, add it to 168, then carry on: 1688 / 902

On to step 6:
The number 902 fits into 1688 1 times, leaving a remainder of 786.
The number 1 becomes the next digit in our result. 
Result so far: 711.0
If we subtract 902 from 1688, we get 786.
Fetch the next digit (7) from the dividend, attach it to 786 and continue: 7867 / 902

Let's proceed to step 7:
902 goes into 7867 8 times with a remainder of 651.
Write down 8 as next digit of the result. 
Result so far: 7118.0
If we subtract 7216 from 7867, we get 651.
Fetch the next digit (5) from the dividend, attach it to 651 and continue: 6515 / 902

On to step 8:
When dividing 6515 by 902, we get 7 with a remainder of 201.
Record the quotient 7 as the next digit in the result. 
Result so far: 71187.0
If we take 6314 away from 6515, we end up with 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 9:
902 goes into 2010 2 times with a remainder of 206.
The number 2 becomes the next digit in our result. 
Result so far: 71187.2
Deduct 1804 from 2010 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 10:
2060 divided by 902 is 2 with a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 71187.22
If we subtract 1804 from 2060, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 71187.22 with a remainder of 0.256.
