Let's divide 72471237 by 86
Our goal is to divide 72471237 by 86.

Going ahead to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 86

Moving on to step 2:
When dividing 72 by 86, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 86

On to step 3:
86 goes into 724 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 688 from 724 and we're left with 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 86

Step 4:
The number 86 fits into 367 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 23 after subtracting 344 from 367.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 86

Step 5:
86 goes into 231 2 times with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 842.0
If we take 172 away from 231, we end up with 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 86

Advancing to step 6:
86 can be fit into 592 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 8426.0
Subtracting 516 from 592 leaves us with 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 86

On to step 7:
763 divided by 86 is 8 with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 84268.0
Deduct 688 from 763 and we're left with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 86

On to step 8:
If we divide 757 by 86, we get 8 and a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 842688.0
If we subtract 688 from 757, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
690 divided by 86 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 842688.8
Subtracting 688 from 690 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
If we divide 20 by 86, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 842688.8
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 86 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 842688.802
Subtracting 172 from 200 leaves us 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.

On to step 12:
86 goes into 280 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 842688.8023
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
86 goes into 220 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 842688.80232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
86 goes into 480 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 842688.802325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
When dividing 500 by 86, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 842688.8023255
Subtract 430 from 500 to get 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 result is 842688.8023255 with a remainder of 7e-07.
