We're dividing 71568348 by 631 
The aim is to understand the frequency of 631 in 71568348.

Let's proceed to step 1:
When dividing 7 by 631, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 631

Step 2:
The number 631 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 631

Moving on to step 3:
When dividing 715 by 631, we get 1 with a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 84 after subtracting 631 from 715.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 631

Moving on to step 4:
846 divided by 631 is 1 with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 631 away from 846, we end up with 215.
Include the next digit (8) from the dividend after 215, then repeat: 2158 / 631

Going ahead to step 5:
The number 631 fits into 2158 3 times, leaving a remainder of 265.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
The remainder is 265 after subtracting 1893 from 2158.
Grab the next digit (3) from the dividend, add it to 265, then carry on: 2653 / 631

Let's proceed to step 6:
631 goes into 2653 4 times with a remainder of 129.
The next digit of our result is 4. 
Result so far: 1134.0
If we subtract 2524 from 2653, we get 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 631

Let's proceed to step 7:
631 goes into 1294 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 11342.0
Subtract 1262 from 1294 to get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 631

Let's proceed to step 8:
631 can be fit into 328 0 times, resulting in a remainder of 328.
Put 0 as the next digit of the answer. 
Result so far: 113420.0
If we take 0 away from 328, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 9:
631 goes into 3280 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 113420.5
If we subtract 3155 from 3280, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 10:
The number 631 fits into 1250 1 times, leaving a remainder of 619.
The next digit of our result is 1. 
Result so far: 113420.51
If we take 631 away from 1250, we end up with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 11:
6190 divided by 631 is 9 with a remainder of 511.
The next digit of our result is 9. 
Result so far: 113420.519
Subtract 5679 from 6190 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 12:
The number 631 fits into 5110 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 113420.5198
Subtract 5048 from 5110 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
If we divide 620 by 631, we get 0 and a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 113420.5198
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
6200 divided by 631 is 9 with a remainder of 521.
Record the quotient 9 as the next digit in the result. 
Result so far: 113420.519809
The remainder is 521 after subtracting 5679 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Step 15:
631 can be fit into 5210 8 times, resulting in a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 113420.5198098
Deduct 5048 from 5210 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 16:
631 goes into 1620 2 times with a remainder of 358.
The number 2 becomes the next digit in our result. 
Result so far: 113420.51980982
Subtract 1262 from 1620 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

The final outcome is 113420.51980982, with a leftover of 3.58e-07.
