Let's divide 16102989 by 257
We want to figure out the number of times 16102989 can be divided by 257.

On to step 1:
When dividing 1 by 257, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 257

Going ahead to step 2:
16 divided by 257 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 257

Let's proceed to step 3:
257 goes into 161 0 times with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Grab the next digit (0) from the dividend, add it to 161, then carry on: 1610 / 257

On to step 4:
1610 divided by 257 is 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 1542 from 1610, we get 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 257

Advancing to step 5:
257 goes into 682 2 times with a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 514 away from 682, we end up with 168.
Grab the next digit (9) from the dividend, add it to 168, then carry on: 1689 / 257

Step 6:
The number 257 fits into 1689 6 times, leaving a remainder of 147.
Use 6 as the next digit of our solution. 
Result so far: 626.0
If we take 1542 away from 1689, we end up with 147.
Append the next digit (8) from the dividend to 147 and continue with: 1478 / 257

Let's proceed to step 7:
The number 257 fits into 1478 5 times, leaving a remainder of 193.
The number 5 becomes the next digit in our result. 
Result so far: 6265.0
Subtract 1285 from 1478 to get 193.
Grab the next digit (9) from the dividend, add it to 193, then carry on: 1939 / 257

Let's proceed to step 8:
If we divide 1939 by 257, we get 7 and a remainder of 140.
The next digit of our result is 7. 
Result so far: 62657.0
Subtracting 1799 from 1939 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
1400 divided by 257 is 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 62657.5
Deduct 1285 from 1400 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 10:
1150 divided by 257 is 4 with a remainder of 122.
The next digit of our result is 4. 
Result so far: 62657.54
If we subtract 1028 from 1150, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 11:
The number 257 fits into 1220 4 times, leaving a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 62657.544
If we take 1028 away from 1220, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 62657.544, with a leftover of 0.0192.
