634691 ÷ 71 
The aim is to understand the frequency of 71 in 634691.

Step 1:
6 divided by 71 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 71

On to step 2:
If we divide 63 by 71, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 71

On to step 3:
634 divided by 71 is 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 66 after subtracting 568 from 634.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 71

On to step 4:
The number 71 fits into 666 9 times, leaving a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 639 away from 666, we end up with 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 71

Moving on to step 5:
71 goes into 279 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 893.0
If we subtract 213 from 279, we get 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 71

Advancing to step 6:
If we divide 661 by 71, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 8939.0
If we subtract 639 from 661, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
220 divided by 71 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 8939.3
If we subtract 213 from 220, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 71, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 8939.3
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
When dividing 700 by 71, we get 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 8939.309
If we subtract 639 from 700, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
If we divide 610 by 71, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 8939.3098
Subtracting 568 from 610 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
71 can be fit into 420 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 8939.30985
The remainder is 65 after subtracting 355 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
71 goes into 650 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 8939.309859
Deduct 639 from 650 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
If we divide 110 by 71, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 8939.3098591
If we subtract 71 from 110, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
71 goes into 390 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8939.30985915
The remainder is 35 after subtracting 355 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 8939.30985915 with a remainder of 3.5e-08.
