138508 divided by 91 
We want to divide 138508 by 91.

Advancing to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 91

Advancing to step 2:
13 divided by 91 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 91

Advancing to step 3:
138 divided by 91 is 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 91 from 138 leaves us with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 91

Going ahead to step 4:
475 divided by 91 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 455 from 475 and we're left with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 91

Advancing to step 5:
The number 91 fits into 200 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtract 182 from 200 to get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 91

Going ahead to step 6:
91 can be fit into 188 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1522.0
Subtract 182 from 188 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 91 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1522.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 91, we get 6 and a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 1522.06
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
540 divided by 91 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 1522.065
Deduct 455 from 540 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
The number 91 fits into 850 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 1522.0659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
91 goes into 310 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1522.06593
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
91 goes into 370 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1522.065934
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 91 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1522.065934
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
When dividing 600 by 91, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 1522.06593406
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 1522.06593406 with a remainder of 5.4e-08.
