We're dividing 136770 by 91 
We're looking to find how many times 91 goes into 136770.

Step 1:
91 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 91

On to step 2:
If we divide 13 by 91, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 91

Step 3:
The number 91 fits into 136 1 times, leaving a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 91 from 136, we get 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 91

Going ahead to step 4:
91 can be fit into 457 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 455 from 457 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 91

Moving on to step 5:
When dividing 27 by 91, we get 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we take 0 away from 27, we end up with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 91

Let's proceed to step 6:
270 divided by 91 is 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 1502.0
If we subtract 182 from 270, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 7:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 1502.9
Deduct 819 from 880 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
91 can be fit into 610 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1502.96
Deduct 546 from 610 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
91 goes into 640 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1502.967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 91, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1502.967
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 91 fits into 300 3 times, leaving a remainder of 27.
The next digit of our result is 3. 
Result so far: 1502.96703
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
If we divide 270 by 91, we get 2 and a remainder of 88.
The next digit of our result is 2. 
Result so far: 1502.967032
The remainder is 88 after subtracting 182 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
91 goes into 880 9 times with a remainder of 61.
The next digit of our result is 9. 
Result so far: 1502.9670329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
The number 91 fits into 610 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1502.96703296
Subtracting 546 from 610 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 1502.96703296, and the remainder is 6.4e-08.
