Let's divide 90596378 by 591
Our goal is to divide 90596378 by 591.

Going ahead to step 1:
When dividing 9 by 591, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 591

On to step 2:
The number 591 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 591

Let's proceed to step 3:
The number 591 fits into 905 1 times, leaving a remainder of 314.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 314 after subtracting 591 from 905.
Include the next digit (9) from the dividend after 314, then repeat: 3149 / 591

On to step 4:
The number 591 fits into 3149 5 times, leaving a remainder of 194.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 194 after subtracting 2955 from 3149.
Grab the next digit (6) from the dividend, add it to 194, then carry on: 1946 / 591

On to step 5:
591 goes into 1946 3 times with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Deduct 1773 from 1946 and we're left with 173.
Include the next digit (3) from the dividend after 173, then repeat: 1733 / 591

On to step 6:
When dividing 1733 by 591, we get 2 with a remainder of 551.
The next digit of our result is 2. 
Result so far: 1532.0
Subtract 1182 from 1733 to get 551.
Append the next digit (7) from the dividend to 551 and continue with: 5517 / 591

On to step 7:
If we divide 5517 by 591, we get 9 and a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 15329.0
If we subtract 5319 from 5517, we get 198.
Take the next digit (8) from the dividend and append it to 198, then repeat: 1988 / 591

Advancing to step 8:
591 goes into 1988 3 times with a remainder of 215.
The next digit of our result is 3. 
Result so far: 153293.0
Subtract 1773 from 1988 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
When dividing 2150 by 591, we get 3 with a remainder of 377.
The next digit of our result is 3. 
Result so far: 153293.3
If we subtract 1773 from 2150, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 10:
The number 591 fits into 3770 6 times, leaving a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 153293.36
If we subtract 3546 from 3770, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 11:
The number 591 fits into 2240 3 times, leaving a remainder of 467.
Put 3 as the next digit of the answer. 
Result so far: 153293.363
If we subtract 1773 from 2240, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 12:
The number 591 fits into 4670 7 times, leaving a remainder of 533.
The number 7 becomes the next digit in our result. 
Result so far: 153293.3637
Subtract 4137 from 4670 to get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Going ahead to step 13:
591 goes into 5330 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 153293.36379
If we take 5319 away from 5330, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
If we divide 110 by 591, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 153293.36379
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 15:
If we divide 1100 by 591, we get 1 and a remainder of 509.
Record the quotient 1 as the next digit in the result. 
Result so far: 153293.3637901
Subtract 591 from 1100 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 16:
591 can be fit into 5090 8 times, resulting in a remainder of 362.
Record the quotient 8 as the next digit in the result. 
Result so far: 153293.36379018
If we take 4728 away from 5090, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final result is 153293.36379018 with a remainder of 3.62e-07.
