84109587 ÷ 71 
The aim is to understand the frequency of 71 in 84109587.

On to step 1:
71 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 71

Advancing to step 2:
When dividing 84 by 71, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 71 from 84 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 71

Step 3:
The number 71 fits into 131 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 71 away from 131, we end up with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 71

Let's proceed to step 4:
600 divided by 71 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtract 568 from 600 to get 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 71

Let's proceed to step 5:
329 divided by 71 is 4 with a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 1184.0
Subtract 284 from 329 to get 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 71

On to step 6:
71 can be fit into 455 6 times, resulting in a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 11846.0
Subtract 426 from 455 to get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 71

Moving on to step 7:
If we divide 298 by 71, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 118464.0
If we subtract 284 from 298, we get 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 71

Step 8:
147 divided by 71 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 1184642.0
If we take 142 away from 147, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
71 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1184642.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
71 can be fit into 500 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1184642.07
Deduct 497 from 500 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
The number 71 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 1184642.07
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
71 can be fit into 300 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1184642.0704
The remainder is 16 after subtracting 284 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
71 can be fit into 160 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1184642.07042
Subtract 142 from 160 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
The number 71 fits into 180 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 1184642.070422
Subtracting 142 from 180 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 1184642.070422, and the remainder is 3.8e-06.
