1 divided by 191 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 191

Going ahead to step 2:
When dividing 13 by 191, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 191

On to step 3:
135 divided by 191 is 0 with a remainder of 135.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 135, we end up with 135.
Append the next digit (6) from the dividend to 135 and continue with: 1356 / 191

On to step 4:
If we divide 1356 by 191, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 1337 from 1356 and we're left with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 191

Going ahead to step 5:
When dividing 198 by 191, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 7 after subtracting 191 from 198.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 191

On to step 6:
75 divided by 191 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 710.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 191

Let's proceed to step 7:
The number 191 fits into 756 3 times, leaving a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 7103.0
If we subtract 573 from 756, we get 183.
Grab the next digit (3) from the dividend, add it to 183, then carry on: 1833 / 191

Moving on to step 8:
If we divide 1833 by 191, we get 9 and a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 71039.0
If we take 1719 away from 1833, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 9:
191 can be fit into 1140 5 times, resulting in a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 71039.5
If we subtract 955 from 1140, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
When dividing 1850 by 191, we get 9 with a remainder of 131.
Write down 9 as next digit of the result. 
Result so far: 71039.59
Subtract 1719 from 1850 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 11:
When dividing 1310 by 191, we get 6 with a remainder of 164.
The next digit of our result is 6. 
Result so far: 71039.596
Subtract 1146 from 1310 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 12:
When dividing 1640 by 191, we get 8 with a remainder of 112.
The next digit of our result is 8. 
Result so far: 71039.5968
If we take 1528 away from 1640, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
191 can be fit into 1120 5 times, resulting in a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 71039.59685
Deduct 955 from 1120 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
191 can be fit into 1650 8 times, resulting in a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 71039.596858
Subtract 1528 from 1650 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 15:
When dividing 1220 by 191, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 71039.5968586
Subtract 1146 from 1220 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 16:
If we divide 740 by 191, we get 3 and a remainder of 167.
Record the quotient 3 as the next digit in the result. 
Result so far: 71039.59685863
The remainder is 167 after subtracting 573 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

The final result is 71039.59685863 with a remainder of 1.67e-07.
