We divide 288643 by 91
We want to figure out the number of times 288643 can be divided by 91.

Going ahead to step 1:
2 divided by 91 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 91

Step 2:
91 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 91

Going ahead to step 3:
288 divided by 91 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 273 from 288, we get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 91

Going ahead to step 4:
91 can be fit into 156 1 times, resulting in a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 91 from 156 and we're left with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 91

Advancing to step 5:
The number 91 fits into 654 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 317.0
The remainder is 17 after subtracting 637 from 654.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 91

Advancing to step 6:
When dividing 173 by 91, we get 1 with a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 3171.0
Deduct 91 from 173 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 7:
If we divide 820 by 91, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3171.9
If we take 819 away from 820, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
10 divided by 91 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3171.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 91, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 3171.901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
When dividing 90 by 91, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 3171.901
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
91 can be fit into 900 9 times, resulting in a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 3171.90109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 12:
91 goes into 810 8 times with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 3171.901098
If we take 728 away from 810, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 13:
If we divide 820 by 91, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 3171.9010989
Subtracting 819 from 820 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
10 divided by 91 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3171.9010989
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 3171.9010989, with a leftover of 1e-08.
