Let's divide 84990137 by 257
We want to figure out the number of times 84990137 can be divided by 257.

Let's proceed to step 1:
If we divide 8 by 257, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 257

On to step 2:
257 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 257

On to step 3:
When dividing 849 by 257, we get 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 771 away from 849, we end up with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 257

Going ahead to step 4:
257 goes into 789 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we subtract 771 from 789, we get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 257

Step 5:
257 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 330.0
If we subtract 0 from 180, we get 180.
Bring next digit (1) of the dividend behind the 180 and repeat the process: 1801 / 257

On to step 6:
257 goes into 1801 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 3307.0
Subtract 1799 from 1801 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 257

Advancing to step 7:
257 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 33070.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 257

Advancing to step 8:
The number 257 fits into 237 0 times, leaving a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 330700.0
If we subtract 0 from 237, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 9:
The number 257 fits into 2370 9 times, leaving a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 330700.9
Subtracting 2313 from 2370 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
570 divided by 257 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 330700.92
If we take 514 away from 570, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
The number 257 fits into 560 2 times, leaving a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 330700.922
If we take 514 away from 560, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 330700.922 with a remainder of 0.0046.
