We divide 91345243 by 538
We want to figure out the number of times 91345243 can be divided by 538.

Going ahead to step 1:
538 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 538

Step 2:
538 can be fit into 91 0 times, resulting in a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 538

On to step 3:
The number 538 fits into 913 1 times, leaving a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 375 after subtracting 538 from 913.
Fetch the next digit (4) from the dividend, attach it to 375 and continue: 3754 / 538

On to step 4:
3754 divided by 538 is 6 with a remainder of 526.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 526 after subtracting 3228 from 3754.
Take the next digit (5) from the dividend and append it to 526, then repeat: 5265 / 538

Advancing to step 5:
When dividing 5265 by 538, we get 9 with a remainder of 423.
Put 9 as the next digit of the answer. 
Result so far: 169.0
Subtracting 4842 from 5265 leaves us with 423.
Include the next digit (2) from the dividend after 423, then repeat: 4232 / 538

Going ahead to step 6:
4232 divided by 538 is 7 with a remainder of 466.
The next digit of our result is 7. 
Result so far: 1697.0
Deduct 3766 from 4232 and we're left with 466.
Grab the next digit (4) from the dividend, add it to 466, then carry on: 4664 / 538

Let's proceed to step 7:
4664 divided by 538 is 8 with a remainder of 360.
The next digit of our result is 8. 
Result so far: 16978.0
If we take 4304 away from 4664, we end up with 360.
Append the next digit (3) from the dividend to 360 and continue with: 3603 / 538

On to step 8:
538 goes into 3603 6 times with a remainder of 375.
Use 6 as the next digit of our solution. 
Result so far: 169786.0
The remainder is 375 after subtracting 3228 from 3603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
3750 divided by 538 is 6 with a remainder of 522.
Put 6 as the next digit of the answer. 
Result so far: 169786.6
Subtract 3228 from 3750 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 10:
5220 divided by 538 is 9 with a remainder of 378.
The next digit of our result is 9. 
Result so far: 169786.69
The remainder is 378 after subtracting 4842 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 11:
If we divide 3780 by 538, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 169786.697
Deduct 3766 from 3780 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
538 goes into 140 0 times with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 169786.697
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
The number 538 fits into 1400 2 times, leaving a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 169786.69702
Subtract 1076 from 1400 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 14:
538 can be fit into 3240 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 169786.697026
If we take 3228 away from 3240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
538 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 169786.697026
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
1200 divided by 538 is 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 169786.69702602
Deduct 1076 from 1200 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 169786.69702602, with a leftover of 1.24e-07.
