87103270 divided by 71 
The aim is to understand the frequency of 71 in 87103270.

Advancing to step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 71

Going ahead to step 2:
The number 71 fits into 87 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 71 from 87, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 71

Step 3:
If we divide 161 by 71, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 142 from 161, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 71

Let's proceed to step 4:
71 goes into 190 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 142 from 190 to get 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 71

Moving on to step 5:
71 can be fit into 483 6 times, resulting in a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 1226.0
Subtract 426 from 483 to get 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 71

Step 6:
When dividing 572 by 71, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 12268.0
If we subtract 568 from 572, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 71

Going ahead to step 7:
The number 71 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 122680.0
Deduct 0 from 47 and we're left with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 71

Moving on to step 8:
The number 71 fits into 470 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1226806.0
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.

Step 9:
When dividing 440 by 71, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1226806.6
If we take 426 away from 440, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
140 divided by 71 is 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 1226806.61
Deduct 71 from 140 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
71 can be fit into 690 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 1226806.619
If we take 639 away from 690, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
The number 71 fits into 510 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1226806.6197
Deduct 497 from 510 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
If we divide 130 by 71, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1226806.61971
The remainder is 59 after subtracting 71 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 14:
When dividing 590 by 71, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1226806.619718
If we take 568 away from 590, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
If we divide 220 by 71, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1226806.6197183
Subtracting 213 from 220 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 16:
If we divide 70 by 71, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1226806.6197183
If we take 0 away from 70, we end up 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.

The final outcome is 1226806.6197183, with a leftover of 7e-08.
