We're dividing 251989 by 91 
Let's see how many times 91 fits into 251989.

Step 1:
91 goes into 2 0 times 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.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 91

Advancing to step 2:
91 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 91

Moving on to step 3:
91 can be fit into 251 2 times, resulting in a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 182 from 251 to get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 91

Moving on to step 4:
When dividing 699 by 91, we get 7 with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 637 from 699 and we're left with 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 91

On to step 5:
91 can be fit into 628 6 times, resulting in a remainder of 82.
The next digit of our result is 6. 
Result so far: 276.0
Deduct 546 from 628 and we're left with 82.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 91

Going ahead to step 6:
91 goes into 829 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 2769.0
Deduct 819 from 829 and we're left 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.

Let's proceed to step 7:
If we divide 100 by 91, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 2769.1
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
If we divide 90 by 91, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 2769.1
Subtracting 0 from 90 leaves us 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.

Advancing to step 9:
If we divide 900 by 91, we get 9 and a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 2769.109
If we subtract 819 from 900, we 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.

On to step 10:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 2769.1098
Subtract 728 from 810 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2769.10989
Deduct 819 from 820 and we're left 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 12:
91 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2769.10989
If we subtract 0 from 10, we 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.

Advancing to step 13:
100 divided by 91 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 2769.1098901
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.

Let's proceed to step 14:
If we divide 90 by 91, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 2769.1098901
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

In conclusion, the division gives 2769.1098901 with a balance of 9e-08.
