We look at the division of 91510242 by 722 
Our goal is to divide 91510242 by 722.

Step 1:
The number 722 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 722

Let's proceed to step 2:
When dividing 91 by 722, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 722

On to step 3:
722 goes into 915 1 times with a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 722 from 915 to get 193.
Bring next digit (1) of the dividend behind the 193 and repeat the process: 1931 / 722

On to step 4:
1931 divided by 722 is 2 with a remainder of 487.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1444 from 1931, we get 487.
Append the next digit (0) from the dividend to 487 and continue with: 4870 / 722

On to step 5:
722 can be fit into 4870 6 times, resulting in a remainder of 538.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtract 4332 from 4870 to get 538.
Take the next digit (2) from the dividend and append it to 538, then repeat: 5382 / 722

On to step 6:
The number 722 fits into 5382 7 times, leaving a remainder of 328.
Record the quotient 7 as the next digit in the result. 
Result so far: 1267.0
Subtracting 5054 from 5382 leaves us with 328.
Fetch the next digit (4) from the dividend, attach it to 328 and continue: 3284 / 722

Step 7:
If we divide 3284 by 722, we get 4 and a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 12674.0
Subtracting 2888 from 3284 leaves us with 396.
Grab the next digit (2) from the dividend, add it to 396, then carry on: 3962 / 722

On to step 8:
722 can be fit into 3962 5 times, resulting in a remainder of 352.
Use 5 as the next digit of our solution. 
Result so far: 126745.0
Subtract 3610 from 3962 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 9:
3520 divided by 722 is 4 with a remainder of 632.
Use 4 as the next digit of our solution. 
Result so far: 126745.4
Deduct 2888 from 3520 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 10:
722 goes into 6320 8 times with a remainder of 544.
Write down 8 as next digit of the result. 
Result so far: 126745.48
If we take 5776 away from 6320, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 11:
The number 722 fits into 5440 7 times, leaving a remainder of 386.
Put 7 as the next digit of the answer. 
Result so far: 126745.487
If we take 5054 away from 5440, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 12:
If we divide 3860 by 722, we get 5 and a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 126745.4875
Subtract 3610 from 3860 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
If we divide 2500 by 722, we get 3 and a remainder of 334.
The next digit of our result is 3. 
Result so far: 126745.48753
Deduct 2166 from 2500 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 14:
If we divide 3340 by 722, we get 4 and a remainder of 452.
The next digit of our result is 4. 
Result so far: 126745.487534
If we take 2888 away from 3340, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 15:
If we divide 4520 by 722, we get 6 and a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 126745.4875346
If we take 4332 away from 4520, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 16:
If we divide 1880 by 722, we get 2 and a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 126745.48753462
If we take 1444 away from 1880, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

After the division, we end up with 126745.48753462 and a remainder of 4.36e-07.
