72090440 ÷ 712 
Our goal is to divide 72090440 by 712.

Going ahead to step 1:
If we divide 7 by 712, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 712

On to step 2:
The number 712 fits into 72 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 712

On to step 3:
712 can be fit into 720 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 712 from 720 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 712

Let's proceed to step 4:
If we divide 89 by 712, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 89, we get 89.
Include the next digit (0) from the dividend after 89, then repeat: 890 / 712

Moving on to step 5:
890 divided by 712 is 1 with a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtracting 712 from 890 leaves us with 178.
Take the next digit (4) from the dividend and append it to 178, then repeat: 1784 / 712

Moving on to step 6:
The number 712 fits into 1784 2 times, leaving a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 1012.0
If we take 1424 away from 1784, we end up with 360.
Grab the next digit (4) from the dividend, add it to 360, then carry on: 3604 / 712

Moving on to step 7:
712 can be fit into 3604 5 times, resulting in a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 10125.0
If we subtract 3560 from 3604, we get 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 712

Step 8:
440 divided by 712 is 0 with a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 101250.0
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 9:
712 can be fit into 4400 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 101250.6
Subtracting 4272 from 4400 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 10:
1280 divided by 712 is 1 with a remainder of 568.
The number 1 becomes the next digit in our result. 
Result so far: 101250.61
If we subtract 712 from 1280, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 11:
5680 divided by 712 is 7 with a remainder of 696.
Use 7 as the next digit of our solution. 
Result so far: 101250.617
The remainder is 696 after subtracting 4984 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 12:
6960 divided by 712 is 9 with a remainder of 552.
Write down 9 as next digit of the result. 
Result so far: 101250.6179
Deduct 6408 from 6960 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 13:
If we divide 5520 by 712, we get 7 and a remainder of 536.
Record the quotient 7 as the next digit in the result. 
Result so far: 101250.61797
The remainder is 536 after subtracting 4984 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 14:
When dividing 5360 by 712, we get 7 with a remainder of 376.
The next digit of our result is 7. 
Result so far: 101250.617977
Subtracting 4984 from 5360 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

After the division, we end up with 101250.617977 and a remainder of 3.76e-05.
