We look at the division of 77410594 by 901 
The aim is to understand the frequency of 901 in 77410594.

Advancing to step 1:
The number 901 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 901

Let's proceed to step 2:
When dividing 77 by 901, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 901

Let's proceed to step 3:
774 divided by 901 is 0 with a remainder of 774.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 774 after subtracting 0 from 774.
Take the next digit (1) from the dividend and append it to 774, then repeat: 7741 / 901

On to step 4:
901 can be fit into 7741 8 times, resulting in a remainder of 533.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7208 from 7741 and we're left with 533.
Fetch the next digit (0) from the dividend, attach it to 533 and continue: 5330 / 901

Going ahead to step 5:
5330 divided by 901 is 5 with a remainder of 825.
The next digit of our result is 5. 
Result so far: 85.0
Subtracting 4505 from 5330 leaves us with 825.
Grab the next digit (5) from the dividend, add it to 825, then carry on: 8255 / 901

Advancing to step 6:
The number 901 fits into 8255 9 times, leaving a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 859.0
The remainder is 146 after subtracting 8109 from 8255.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 901

Going ahead to step 7:
901 goes into 1469 1 times with a remainder of 568.
Put 1 as the next digit of the answer. 
Result so far: 8591.0
Deduct 901 from 1469 and we're left with 568.
Take the next digit (4) from the dividend and append it to 568, then repeat: 5684 / 901

Moving on to step 8:
When dividing 5684 by 901, we get 6 with a remainder of 278.
The number 6 becomes the next digit in our result. 
Result so far: 85916.0
Subtract 5406 from 5684 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 9:
If we divide 2780 by 901, we get 3 and a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 85916.3
Subtracting 2703 from 2780 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
When dividing 770 by 901, we get 0 with a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 85916.3
If we take 0 away from 770, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 11:
When dividing 7700 by 901, we get 8 with a remainder of 492.
The next digit of our result is 8. 
Result so far: 85916.308
If we subtract 7208 from 7700, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 12:
4920 divided by 901 is 5 with a remainder of 415.
The next digit of our result is 5. 
Result so far: 85916.3085
The remainder is 415 after subtracting 4505 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 13:
If we divide 4150 by 901, we get 4 and a remainder of 546.
Put 4 as the next digit of the answer. 
Result so far: 85916.30854
If we subtract 3604 from 4150, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 14:
When dividing 5460 by 901, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 85916.308546
The remainder is 54 after subtracting 5406 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 15:
When dividing 540 by 901, we get 0 with a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 85916.308546
Deduct 0 from 540 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 16:
The number 901 fits into 5400 5 times, leaving a remainder of 895.
Record the quotient 5 as the next digit in the result. 
Result so far: 85916.30854605
If we take 4505 away from 5400, we end up with 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

After the division, we end up with 85916.30854605 and a remainder of 8.95e-07.
