We're dividing 90991049 by 849 
We want to divide 90991049 by 849.

On to step 1:
The number 849 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 849

On to step 2:
The number 849 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 849

On to step 3:
909 divided by 849 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 849 from 909 to get 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 849

Advancing to step 4:
When dividing 609 by 849, we get 0 with a remainder of 609.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 609 leaves us with 609.
Bring next digit (1) of the dividend behind the 609 and repeat the process: 6091 / 849

Going ahead to step 5:
When dividing 6091 by 849, we get 7 with a remainder of 148.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 5943 from 6091 to get 148.
Append the next digit (0) from the dividend to 148 and continue with: 1480 / 849

Step 6:
849 can be fit into 1480 1 times, resulting in a remainder of 631.
Write down 1 as next digit of the result. 
Result so far: 1071.0
Subtracting 849 from 1480 leaves us with 631.
Fetch the next digit (4) from the dividend, attach it to 631 and continue: 6314 / 849

Step 7:
When dividing 6314 by 849, we get 7 with a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 10717.0
Subtract 5943 from 6314 to get 371.
Include the next digit (9) from the dividend after 371, then repeat: 3719 / 849

Going ahead to step 8:
849 can be fit into 3719 4 times, resulting in a remainder of 323.
Use 4 as the next digit of our solution. 
Result so far: 107174.0
Subtract 3396 from 3719 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 9:
849 goes into 3230 3 times with a remainder of 683.
Write down 3 as next digit of the result. 
Result so far: 107174.3
Subtract 2547 from 3230 to get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Going ahead to step 10:
849 goes into 6830 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 107174.38
Deduct 6792 from 6830 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 849, we get 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 107174.38
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 12:
3800 divided by 849 is 4 with a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 107174.3804
Subtracting 3396 from 3800 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 13:
849 can be fit into 4040 4 times, resulting in a remainder of 644.
Put 4 as the next digit of the answer. 
Result so far: 107174.38044
If we take 3396 away from 4040, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

The final outcome is 107174.38044, with a leftover of 0.000644.
