Let's divide 73129631 by 901
We're looking to find how many times 901 goes into 73129631.

On to step 1:
If we divide 7 by 901, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 901

Step 2:
If we divide 73 by 901, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 901

Going ahead to step 3:
If we divide 731 by 901, we get 0 and a remainder of 731.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 731 after subtracting 0 from 731.
Fetch the next digit (2) from the dividend, attach it to 731 and continue: 7312 / 901

Let's proceed to step 4:
When dividing 7312 by 901, we get 8 with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7208 from 7312 and we're left with 104.
Include the next digit (9) from the dividend after 104, then repeat: 1049 / 901

Let's proceed to step 5:
The number 901 fits into 1049 1 times, leaving a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 901 from 1049, we get 148.
Take the next digit (6) from the dividend and append it to 148, then repeat: 1486 / 901

Advancing to step 6:
1486 divided by 901 is 1 with a remainder of 585.
Put 1 as the next digit of the answer. 
Result so far: 811.0
Deduct 901 from 1486 and we're left with 585.
Bring next digit (3) of the dividend behind the 585 and repeat the process: 5853 / 901

Step 7:
901 can be fit into 5853 6 times, resulting in a remainder of 447.
Record the quotient 6 as the next digit in the result. 
Result so far: 8116.0
If we take 5406 away from 5853, we end up with 447.
Bring next digit (1) of the dividend behind the 447 and repeat the process: 4471 / 901

Let's proceed to step 8:
901 can be fit into 4471 4 times, resulting in a remainder of 867.
Record the quotient 4 as the next digit in the result. 
Result so far: 81164.0
Subtract 3604 from 4471 to get 867.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

Going ahead to step 9:
8670 divided by 901 is 9 with a remainder of 561.
Use 9 as the next digit of our solution. 
Result so far: 81164.9
Subtract 8109 from 8670 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Going ahead to step 10:
If we divide 5610 by 901, we get 6 and a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 81164.96
If we take 5406 away from 5610, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
2040 divided by 901 is 2 with a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 81164.962
Deduct 1802 from 2040 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 12:
901 goes into 2380 2 times with a remainder of 578.
Record the quotient 2 as the next digit in the result. 
Result so far: 81164.9622
If we subtract 1802 from 2380, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The quotient of the division is 81164.9622, and the remainder is 0.00578.
