Let's divide 76645851 by 901
The aim is to understand the frequency of 901 in 76645851.

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
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 901

Moving on to step 2:
901 goes into 76 0 times with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 901

Step 3:
901 goes into 766 0 times with a remainder of 766.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 766 to get 766.
Grab the next digit (4) from the dividend, add it to 766, then carry on: 7664 / 901

Let's proceed to step 4:
7664 divided by 901 is 8 with a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7208 from 7664 leaves us with 456.
Take the next digit (5) from the dividend and append it to 456, then repeat: 4565 / 901

On to step 5:
901 goes into 4565 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 85.0
Subtracting 4505 from 4565 leaves us with 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 901

On to step 6:
The number 901 fits into 608 0 times, leaving a remainder of 608.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Deduct 0 from 608 and we're left with 608.
Bring next digit (5) of the dividend behind the 608 and repeat the process: 6085 / 901

On to step 7:
When dividing 6085 by 901, we get 6 with a remainder of 679.
The number 6 becomes the next digit in our result. 
Result so far: 8506.0
Subtract 5406 from 6085 to get 679.
Include the next digit (1) from the dividend after 679, then repeat: 6791 / 901

Moving on to step 8:
If we divide 6791 by 901, we get 7 and a remainder of 484.
Record the quotient 7 as the next digit in the result. 
Result so far: 85067.0
If we subtract 6307 from 6791, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 9:
If we divide 4840 by 901, we get 5 and a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 85067.5
If we take 4505 away from 4840, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 10:
901 goes into 3350 3 times with a remainder of 647.
Write down 3 as next digit of the result. 
Result so far: 85067.53
Subtracting 2703 from 3350 leaves us with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Let's proceed to step 11:
The number 901 fits into 6470 7 times, leaving a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 85067.537
If we take 6307 away from 6470, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 12:
If we divide 1630 by 901, we get 1 and a remainder of 729.
The number 1 becomes the next digit in our result. 
Result so far: 85067.5371
The remainder is 729 after subtracting 901 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Step 13:
7290 divided by 901 is 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 85067.53718
If we subtract 7208 from 7290, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
The number 901 fits into 820 0 times, leaving a remainder of 820.
The number 0 becomes the next digit in our result. 
Result so far: 85067.53718
If we subtract 0 from 820, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 15:
If we divide 8200 by 901, we get 9 and a remainder of 91.
The next digit of our result is 9. 
Result so far: 85067.5371809
If we subtract 8109 from 8200, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 16:
The number 901 fits into 910 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 85067.53718091
Deduct 901 from 910 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 85067.53718091, and the remainder is 9e-09.
