154903 ÷ 91 
We're looking to find how many times 91 goes into 154903.

Advancing to step 1:
When dividing 1 by 91, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 91

Step 2:
When dividing 15 by 91, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 91

Moving on to step 3:
When dividing 154 by 91, we get 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 91 away from 154, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 91

Going ahead to step 4:
91 goes into 639 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 637 away from 639, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 91

Let's proceed to step 5:
The number 91 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 91

Let's proceed to step 6:
91 goes into 203 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 1702.0
The remainder is 21 after subtracting 182 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
91 can be fit into 210 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1702.2
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 91, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1702.23
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
91 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 1702.23
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
700 divided by 91 is 7 with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 1702.2307
If we subtract 637 from 700, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
The number 91 fits into 630 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 1702.23076
The remainder is 84 after subtracting 546 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
91 goes into 840 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 1702.230769
If we subtract 819 from 840, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
91 goes into 210 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1702.2307692
Subtract 182 from 210 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
If we divide 280 by 91, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1702.23076923
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 1702.23076923 and a remainder of 7e-09.
