Let's divide 81876129 by 901
We want to figure out the number of times 81876129 can be divided by 901.

Moving on to step 1:
When dividing 8 by 901, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 901

Advancing to step 2:
The number 901 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 901

Advancing to step 3:
818 divided by 901 is 0 with a remainder of 818.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 818 to get 818.
Take the next digit (7) from the dividend and append it to 818, then repeat: 8187 / 901

Let's proceed to step 4:
The number 901 fits into 8187 9 times, leaving a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 78 after subtracting 8109 from 8187.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 901

Step 5:
901 can be fit into 786 0 times, resulting in a remainder of 786.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 786 after subtracting 0 from 786.
Include the next digit (1) from the dividend after 786, then repeat: 7861 / 901

Advancing to step 6:
901 can be fit into 7861 8 times, resulting in a remainder of 653.
The number 8 becomes the next digit in our result. 
Result so far: 908.0
The remainder is 653 after subtracting 7208 from 7861.
Include the next digit (2) from the dividend after 653, then repeat: 6532 / 901

Advancing to step 7:
6532 divided by 901 is 7 with a remainder of 225.
The next digit of our result is 7. 
Result so far: 9087.0
Subtract 6307 from 6532 to get 225.
Include the next digit (9) from the dividend after 225, then repeat: 2259 / 901

Step 8:
2259 divided by 901 is 2 with a remainder of 457.
The number 2 becomes the next digit in our result. 
Result so far: 90872.0
Subtracting 1802 from 2259 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 9:
901 can be fit into 4570 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 90872.5
Subtracting 4505 from 4570 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
901 goes into 650 0 times with a remainder of 650.
The number 0 becomes the next digit in our result. 
Result so far: 90872.5
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 11:
901 goes into 6500 7 times with a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 90872.507
Subtract 6307 from 6500 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 12:
1930 divided by 901 is 2 with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 90872.5072
Subtracting 1802 from 1930 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
901 goes into 1280 1 times with a remainder of 379.
The next digit of our result is 1. 
Result so far: 90872.50721
If we take 901 away from 1280, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 14:
When dividing 3790 by 901, we get 4 with a remainder of 186.
Write down 4 as next digit of the result. 
Result so far: 90872.507214
The remainder is 186 after subtracting 3604 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 15:
When dividing 1860 by 901, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 90872.5072142
Deduct 1802 from 1860 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
580 divided by 901 is 0 with a remainder of 580.
The next digit of our result is 0. 
Result so far: 90872.5072142
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final outcome is 90872.5072142, with a leftover of 5.8e-07.
