Let's divide 86638547 by 901
Our goal is to divide 86638547 by 901.

Step 1:
8 divided by 901 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 901

Step 2:
If we divide 86 by 901, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 901

Moving on to step 3:
The number 901 fits into 866 0 times, leaving a remainder of 866.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 866 after subtracting 0 from 866.
Grab the next digit (3) from the dividend, add it to 866, then carry on: 8663 / 901

Advancing to step 4:
901 can be fit into 8663 9 times, resulting in a remainder of 554.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 8109 from 8663 to get 554.
Bring next digit (8) of the dividend behind the 554 and repeat the process: 5548 / 901

Moving on to step 5:
The number 901 fits into 5548 6 times, leaving a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we take 5406 away from 5548, we end up with 142.
Take the next digit (5) from the dividend and append it to 142, then repeat: 1425 / 901

Going ahead to step 6:
901 goes into 1425 1 times with a remainder of 524.
Put 1 as the next digit of the answer. 
Result so far: 961.0
If we take 901 away from 1425, we end up with 524.
Grab the next digit (4) from the dividend, add it to 524, then carry on: 5244 / 901

Moving on to step 7:
901 goes into 5244 5 times with a remainder of 739.
Use 5 as the next digit of our solution. 
Result so far: 9615.0
The remainder is 739 after subtracting 4505 from 5244.
Grab the next digit (7) from the dividend, add it to 739, then carry on: 7397 / 901

Advancing to step 8:
901 can be fit into 7397 8 times, resulting in a remainder of 189.
Write down 8 as next digit of the result. 
Result so far: 96158.0
Subtracting 7208 from 7397 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
If we divide 1890 by 901, we get 2 and a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 96158.2
Subtract 1802 from 1890 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 10:
901 can be fit into 880 0 times, resulting in a remainder of 880.
Use 0 as the next digit of our solution. 
Result so far: 96158.2
If we subtract 0 from 880, we get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

On to step 11:
The number 901 fits into 8800 9 times, leaving a remainder of 691.
The next digit of our result is 9. 
Result so far: 96158.209
The remainder is 691 after subtracting 8109 from 8800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Advancing to step 12:
When dividing 6910 by 901, we get 7 with a remainder of 603.
The number 7 becomes the next digit in our result. 
Result so far: 96158.2097
If we take 6307 away from 6910, we end up with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Advancing to step 13:
901 goes into 6030 6 times with a remainder of 624.
Put 6 as the next digit of the answer. 
Result so far: 96158.20976
If we take 5406 away from 6030, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 14:
6240 divided by 901 is 6 with a remainder of 834.
Put 6 as the next digit of the answer. 
Result so far: 96158.209766
The remainder is 834 after subtracting 5406 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

The final result is 96158.209766 with a remainder of 8.34e-05.
