91803 ÷ 61 
Our goal is to divide 91803 by 61.

Let's proceed to step 1:
The number 61 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 61

On to step 2:
61 can be fit into 91 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 61 from 91 and we're left with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 61

Going ahead to step 3:
308 divided by 61 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 3 after subtracting 305 from 308.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 61

Going ahead to step 4:
61 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 150.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 61

Going ahead to step 5:
61 goes into 303 4 times with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 1504.0
Subtract 244 from 303 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 6:
If we divide 590 by 61, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 1504.9
Deduct 549 from 590 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
410 divided by 61 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 1504.96
Subtract 366 from 410 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
61 can be fit into 440 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1504.967
Subtracting 427 from 440 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 61, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1504.9672
Subtract 122 from 130 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 61, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1504.96721
If we take 61 away from 80, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
61 can be fit into 190 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1504.967213
Subtract 183 from 190 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
61 can be fit into 70 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1504.9672131
If we take 61 away from 70, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
The number 61 fits into 90 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1504.96721311
If we subtract 61 from 90, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 1504.96721311 with a remainder of 2.9e-08.
