66817164 ÷ 901 
We want to divide 66817164 by 901.

On to step 1:
When dividing 6 by 901, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 901

Step 2:
When dividing 66 by 901, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 901

Moving on to step 3:
901 can be fit into 668 0 times, resulting in a remainder of 668.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 668 and we're left with 668.
Include the next digit (1) from the dividend after 668, then repeat: 6681 / 901

Moving on to step 4:
If we divide 6681 by 901, we get 7 and a remainder of 374.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 374 after subtracting 6307 from 6681.
Append the next digit (7) from the dividend to 374 and continue with: 3747 / 901

On to step 5:
3747 divided by 901 is 4 with a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtracting 3604 from 3747 leaves us with 143.
Grab the next digit (1) from the dividend, add it to 143, then carry on: 1431 / 901

On to step 6:
1431 divided by 901 is 1 with a remainder of 530.
Write down 1 as next digit of the result. 
Result so far: 741.0
Deduct 901 from 1431 and we're left with 530.
Take the next digit (6) from the dividend and append it to 530, then repeat: 5306 / 901

Step 7:
901 goes into 5306 5 times with a remainder of 801.
Write down 5 as next digit of the result. 
Result so far: 7415.0
Deduct 4505 from 5306 and we're left with 801.
Include the next digit (4) from the dividend after 801, then repeat: 8014 / 901

Going ahead to step 8:
The number 901 fits into 8014 8 times, leaving a remainder of 806.
Write down 8 as next digit of the result. 
Result so far: 74158.0
If we subtract 7208 from 8014, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Moving on to step 9:
If we divide 8060 by 901, we get 8 and a remainder of 852.
Write down 8 as next digit of the result. 
Result so far: 74158.8
If we take 7208 away from 8060, we end up with 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

On to step 10:
8520 divided by 901 is 9 with a remainder of 411.
The number 9 becomes the next digit in our result. 
Result so far: 74158.89
Subtract 8109 from 8520 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 11:
4110 divided by 901 is 4 with a remainder of 506.
Record the quotient 4 as the next digit in the result. 
Result so far: 74158.894
Subtract 3604 from 4110 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 12:
If we divide 5060 by 901, we get 5 and a remainder of 555.
Write down 5 as next digit of the result. 
Result so far: 74158.8945
If we take 4505 away from 5060, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 13:
The number 901 fits into 5550 6 times, leaving a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 74158.89456
If we take 5406 away from 5550, we end up 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.

Moving on to step 14:
901 goes into 1440 1 times with a remainder of 539.
The number 1 becomes the next digit in our result. 
Result so far: 74158.894561
Subtracting 901 from 1440 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Moving on to step 15:
When dividing 5390 by 901, we get 5 with a remainder of 885.
The number 5 becomes the next digit in our result. 
Result so far: 74158.8945615
Subtract 4505 from 5390 to get 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Step 16:
901 can be fit into 8850 9 times, resulting in a remainder of 741.
Record the quotient 9 as the next digit in the result. 
Result so far: 74158.89456159
Subtract 8109 from 8850 to get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

The quotient of the division is 74158.89456159, and the remainder is 7.41e-07.
