720073 ÷ 86 
We want to figure out the number of times 720073 can be divided by 86.

Let's proceed to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 86

Moving on to step 2:
72 divided by 86 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 86

On to step 3:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 688 from 720 leaves us with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 86

Step 4:
The number 86 fits into 320 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we subtract 258 from 320, we get 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 86

Going ahead to step 5:
If we divide 627 by 86, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 837.0
Subtracting 602 from 627 leaves us with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 86

Going ahead to step 6:
If we divide 253 by 86, we get 2 and a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 8372.0
Subtracting 172 from 253 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
The number 86 fits into 810 9 times, leaving a remainder of 36.
The next digit of our result is 9. 
Result so far: 8372.9
Subtracting 774 from 810 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 8372.94
Subtract 344 from 360 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.

Advancing to step 9:
86 goes into 160 1 times with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 8372.941
Subtracting 86 from 160 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
86 goes into 740 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8372.9418
Deduct 688 from 740 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.

Moving on to step 11:
The number 86 fits into 520 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 8372.94186
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 86, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8372.94186
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
If we divide 400 by 86, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 8372.9418604
Deduct 344 from 400 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 8372.94186046
If we take 516 away from 560, we end up 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 8372.94186046, and the remainder is 4.4e-08.
