78058578 divided by 901 
We want to figure out the number of times 78058578 can be divided by 901.

Advancing to step 1:
If we divide 7 by 901, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 901

Going ahead to step 2:
78 divided by 901 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 901

Advancing to step 3:
780 divided by 901 is 0 with a remainder of 780.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 780, we get 780.
Take the next digit (5) from the dividend and append it to 780, then repeat: 7805 / 901

Moving on to step 4:
901 can be fit into 7805 8 times, resulting in a remainder of 597.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7208 from 7805, we get 597.
Fetch the next digit (8) from the dividend, attach it to 597 and continue: 5978 / 901

Moving on to step 5:
901 goes into 5978 6 times with a remainder of 572.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 5406 from 5978, we get 572.
Include the next digit (5) from the dividend after 572, then repeat: 5725 / 901

On to step 6:
901 can be fit into 5725 6 times, resulting in a remainder of 319.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
If we take 5406 away from 5725, we end up with 319.
Bring next digit (7) of the dividend behind the 319 and repeat the process: 3197 / 901

On to step 7:
The number 901 fits into 3197 3 times, leaving a remainder of 494.
Record the quotient 3 as the next digit in the result. 
Result so far: 8663.0
If we take 2703 away from 3197, we end up with 494.
Include the next digit (8) from the dividend after 494, then repeat: 4948 / 901

Advancing to step 8:
901 can be fit into 4948 5 times, resulting in a remainder of 443.
The next digit of our result is 5. 
Result so far: 86635.0
If we take 4505 away from 4948, we end up 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.

On to step 9:
When dividing 4430 by 901, we get 4 with a remainder of 826.
Put 4 as the next digit of the answer. 
Result so far: 86635.4
Deduct 3604 from 4430 and we're left 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.

Advancing to step 10:
The number 901 fits into 8260 9 times, leaving a remainder of 151.
The next digit of our result is 9. 
Result so far: 86635.49
Subtracting 8109 from 8260 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 11:
The number 901 fits into 1510 1 times, leaving a remainder of 609.
The next digit of our result is 1. 
Result so far: 86635.491
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.

Going ahead to step 12:
6090 divided by 901 is 6 with a remainder of 684.
Write down 6 as next digit of the result. 
Result so far: 86635.4916
If we take 5406 away from 6090, we end up 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.

Advancing to step 13:
901 goes into 6840 7 times with a remainder of 533.
Put 7 as the next digit of the answer. 
Result so far: 86635.49167
Deduct 6307 from 6840 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

On to step 14:
901 goes into 5330 5 times with a remainder of 825.
Use 5 as the next digit of our solution. 
Result so far: 86635.491675
If we take 4505 away from 5330, we end up with 825.
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:
901 can be fit into 8250 9 times, resulting in a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 86635.4916759
The remainder is 141 after subtracting 8109 from 8250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 16:
If we divide 1410 by 901, we get 1 and a remainder of 509.
Use 1 as the next digit of our solution. 
Result so far: 86635.49167591
The remainder is 509 after subtracting 901 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

The final result is 86635.49167591 with a remainder of 5.09e-07.
