We look at the division of 80388564 by 901 
We want to figure out the number of times 80388564 can be divided by 901.

Let's proceed to step 1:
901 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 901

On to step 2:
901 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 901

Advancing to step 3:
The number 901 fits into 803 0 times, leaving a remainder of 803.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 803 to get 803.
Grab the next digit (8) from the dividend, add it to 803, then carry on: 8038 / 901

Advancing to step 4:
The number 901 fits into 8038 8 times, leaving a remainder of 830.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7208 from 8038, we get 830.
Bring next digit (8) of the dividend behind the 830 and repeat the process: 8308 / 901

Advancing to step 5:
When dividing 8308 by 901, we get 9 with a remainder of 199.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 8109 from 8308 to get 199.
Grab the next digit (5) from the dividend, add it to 199, then carry on: 1995 / 901

Going ahead to step 6:
1995 divided by 901 is 2 with a remainder of 193.
The next digit of our result is 2. 
Result so far: 892.0
Subtract 1802 from 1995 to get 193.
Take the next digit (6) from the dividend and append it to 193, then repeat: 1936 / 901

On to step 7:
901 goes into 1936 2 times with a remainder of 134.
The number 2 becomes the next digit in our result. 
Result so far: 8922.0
If we subtract 1802 from 1936, we get 134.
Include the next digit (4) from the dividend after 134, then repeat: 1344 / 901

Going ahead to step 8:
If we divide 1344 by 901, we get 1 and a remainder of 443.
The next digit of our result is 1. 
Result so far: 89221.0
Deduct 901 from 1344 and we're left with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 9:
901 can be fit into 4430 4 times, resulting in a remainder of 826.
The next digit of our result is 4. 
Result so far: 89221.4
Subtracting 3604 from 4430 leaves us with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Moving on to step 10:
When dividing 8260 by 901, we get 9 with a remainder of 151.
The next digit of our result is 9. 
Result so far: 89221.49
The remainder is 151 after subtracting 8109 from 8260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 11:
If we divide 1510 by 901, we get 1 and a remainder of 609.
The number 1 becomes the next digit in our result. 
Result so far: 89221.491
Subtract 901 from 1510 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Let's proceed to step 12:
The number 901 fits into 6090 6 times, leaving a remainder of 684.
Write down 6 as next digit of the result. 
Result so far: 89221.4916
Subtracting 5406 from 6090 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Moving on to step 13:
The number 901 fits into 6840 7 times, leaving a remainder of 533.
Write down 7 as next digit of the result. 
Result so far: 89221.49167
If we subtract 6307 from 6840, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 14:
901 goes into 5330 5 times with a remainder of 825.
The next digit of our result is 5. 
Result so far: 89221.491675
The remainder is 825 after subtracting 4505 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Moving on to step 15:
When dividing 8250 by 901, we get 9 with a remainder of 141.
The next digit of our result is 9. 
Result so far: 89221.4916759
Subtract 8109 from 8250 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 16:
901 goes into 1410 1 times with a remainder of 509.
Write down 1 as next digit of the result. 
Result so far: 89221.49167591
Deduct 901 from 1410 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

The quotient of the division is 89221.49167591, and the remainder is 5.09e-07.
