We divide 80333924 by 631
The aim is to understand the frequency of 631 in 80333924.

On to step 1:
631 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 631

Moving on to step 2:
If we divide 80 by 631, we get 0 and 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.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 631

Step 3:
631 can be fit into 803 1 times, resulting in a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 631 away from 803, we end up with 172.
Grab the next digit (3) from the dividend, add it to 172, then carry on: 1723 / 631

Moving on to step 4:
1723 divided by 631 is 2 with a remainder of 461.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1262 from 1723 and we're left with 461.
Bring next digit (3) of the dividend behind the 461 and repeat the process: 4613 / 631

Advancing to step 5:
631 can be fit into 4613 7 times, resulting in a remainder of 196.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Deduct 4417 from 4613 and we're left with 196.
Grab the next digit (9) from the dividend, add it to 196, then carry on: 1969 / 631

Advancing to step 6:
631 can be fit into 1969 3 times, resulting in a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 1273.0
Subtracting 1893 from 1969 leaves us with 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 631

Moving on to step 7:
762 divided by 631 is 1 with a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 12731.0
If we take 631 away from 762, we end up with 131.
Take the next digit (4) from the dividend and append it to 131, then repeat: 1314 / 631

Advancing to step 8:
If we divide 1314 by 631, we get 2 and a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 127312.0
Subtract 1262 from 1314 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
If we divide 520 by 631, we get 0 and a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 127312.0
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
631 goes into 5200 8 times with a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 127312.08
Subtracting 5048 from 5200 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 11:
When dividing 1520 by 631, we get 2 with a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 127312.082
Deduct 1262 from 1520 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 12:
2580 divided by 631 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 127312.0824
The remainder is 56 after subtracting 2524 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
631 goes into 560 0 times with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 127312.0824
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 14:
5600 divided by 631 is 8 with a remainder of 552.
Put 8 as the next digit of the answer. 
Result so far: 127312.082408
The remainder is 552 after subtracting 5048 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 15:
When dividing 5520 by 631, we get 8 with a remainder of 472.
Record the quotient 8 as the next digit in the result. 
Result so far: 127312.0824088
If we take 5048 away from 5520, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final result is 127312.0824088 with a remainder of 4.72e-06.
