9851398 ÷ 250 
Our goal is to divide 9851398 by 250.

Step 1:
The number 250 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 250

Let's proceed to step 2:
98 divided by 250 is 0 with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 250

Step 3:
The number 250 fits into 985 3 times, leaving a remainder of 235.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 750 from 985, we get 235.
Take the next digit (1) from the dividend and append it to 235, then repeat: 2351 / 250

Let's proceed to step 4:
If we divide 2351 by 250, we get 9 and a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 2250 from 2351 and we're left with 101.
Fetch the next digit (3) from the dividend, attach it to 101 and continue: 1013 / 250

Advancing to step 5:
If we divide 1013 by 250, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 394.0
Subtracting 1000 from 1013 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 250

On to step 6:
139 divided by 250 is 0 with a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 3940.0
If we subtract 0 from 139, we get 139.
Include the next digit (8) from the dividend after 139, then repeat: 1398 / 250

Advancing to step 7:
The number 250 fits into 1398 5 times, leaving a remainder of 148.
Record the quotient 5 as the next digit in the result. 
Result so far: 39405.0
Subtract 1250 from 1398 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 8:
If we divide 1480 by 250, we get 5 and a remainder of 230.
The next digit of our result is 5. 
Result so far: 39405.5
If we subtract 1250 from 1480, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
250 goes into 2300 9 times with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 39405.59
Deduct 2250 from 2300 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 250, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 39405.592
If we take 500 away from 500, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 250, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39405.592
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
250 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39405.592
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 39405.592, with a leftover of 0.0.
