45421 divided by 71 
The aim is to understand the frequency of 71 in 45421.

Let's proceed to step 1:
The number 71 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 71

Advancing to step 2:
When dividing 45 by 71, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 71

Let's proceed to step 3:
454 divided by 71 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 426 from 454, we get 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 71

Step 4:
71 goes into 282 3 times with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 213 from 282 leaves us with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 71

Let's proceed to step 5:
691 divided by 71 is 9 with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 639.0
Deduct 639 from 691 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 6:
If we divide 520 by 71, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 639.7
Deduct 497 from 520 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 71, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 639.73
The remainder is 17 after subtracting 213 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
170 divided by 71 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 639.732
If we take 142 away from 170, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 71, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 639.7323
Subtract 213 from 280 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
The number 71 fits into 670 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 639.73239
If we take 639 away from 670, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
310 divided by 71 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 639.732394
Subtracting 284 from 310 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
71 goes into 260 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 639.7323943
Subtract 213 from 260 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 13:
470 divided by 71 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 639.73239436
Deduct 426 from 470 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 639.73239436, and the remainder is 4.4e-08.
