We're dividing 91290881 by 739 
We want to figure out the number of times 91290881 can be divided by 739.

Moving on to step 1:
9 divided by 739 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 739

Step 2:
91 divided by 739 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 739

Let's proceed to step 3:
When dividing 912 by 739, we get 1 with a remainder of 173.
The next digit of our result is 1. 
Result so far: 1.0
If we take 739 away from 912, we end up with 173.
Grab the next digit (9) from the dividend, add it to 173, then carry on: 1739 / 739

Let's proceed to step 4:
If we divide 1739 by 739, we get 2 and a remainder of 261.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1478 from 1739 and we're left with 261.
Grab the next digit (0) from the dividend, add it to 261, then carry on: 2610 / 739

Advancing to step 5:
2610 divided by 739 is 3 with a remainder of 393.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 393 after subtracting 2217 from 2610.
Include the next digit (8) from the dividend after 393, then repeat: 3938 / 739

Let's proceed to step 6:
The number 739 fits into 3938 5 times, leaving a remainder of 243.
The next digit of our result is 5. 
Result so far: 1235.0
If we take 3695 away from 3938, we end up with 243.
Append the next digit (8) from the dividend to 243 and continue with: 2438 / 739

On to step 7:
If we divide 2438 by 739, we get 3 and a remainder of 221.
The next digit of our result is 3. 
Result so far: 12353.0
Subtract 2217 from 2438 to get 221.
Bring next digit (1) of the dividend behind the 221 and repeat the process: 2211 / 739

Step 8:
739 goes into 2211 2 times with a remainder of 733.
Use 2 as the next digit of our solution. 
Result so far: 123532.0
If we take 1478 away from 2211, we end up with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Step 9:
739 can be fit into 7330 9 times, resulting in a remainder of 679.
Put 9 as the next digit of the answer. 
Result so far: 123532.9
Subtracting 6651 from 7330 leaves us with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 10:
If we divide 6790 by 739, we get 9 and a remainder of 139.
The next digit of our result is 9. 
Result so far: 123532.99
Subtracting 6651 from 6790 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final result is 123532.99 with a remainder of 0.139.
