869640 ÷ 71 
Let's see how many times 71 fits into 869640.

Step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 71

Step 2:
71 goes into 86 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 71 from 86 to get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 71

Step 3:
71 can be fit into 159 2 times, resulting in a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 142 from 159 and we're left with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 71

Let's proceed to step 4:
When dividing 176 by 71, we get 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we take 142 away from 176, we end up with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 71

Going ahead to step 5:
The number 71 fits into 344 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1224.0
If we take 284 away from 344, we end up with 60.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 71

On to step 6:
The number 71 fits into 600 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 12248.0
If we subtract 568 from 600, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
The number 71 fits into 320 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 12248.4
Subtract 284 from 320 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
360 divided by 71 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12248.45
The remainder is 5 after subtracting 355 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
71 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12248.45
Deduct 0 from 50 and we're left 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.

On to step 10:
71 goes into 500 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 12248.4507
The remainder is 3 after subtracting 497 from 500.
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:
If we divide 30 by 71, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12248.4507
Subtracting 0 from 30 leaves us 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.

Step 12:
300 divided by 71 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 12248.450704
Subtract 284 from 300 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
71 can be fit into 160 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 12248.4507042
The remainder is 18 after subtracting 142 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
71 goes into 180 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 12248.45070422
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.

In conclusion, the division gives 12248.45070422 with a balance of 3.8e-08.
