We're dividing 25275993 by 989 
We want to figure out the number of times 25275993 can be divided by 989.

Let's proceed to step 1:
If we divide 2 by 989, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 989

Let's proceed to step 2:
When dividing 25 by 989, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 989

On to step 3:
The number 989 fits into 252 0 times, leaving a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 252, we get 252.
Bring next digit (7) of the dividend behind the 252 and repeat the process: 2527 / 989

Going ahead to step 4:
If we divide 2527 by 989, we get 2 and a remainder of 549.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1978 from 2527 and we're left with 549.
Append the next digit (5) from the dividend to 549 and continue with: 5495 / 989

On to step 5:
5495 divided by 989 is 5 with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 4945 from 5495 to get 550.
Grab the next digit (9) from the dividend, add it to 550, then carry on: 5509 / 989

Advancing to step 6:
989 can be fit into 5509 5 times, resulting in a remainder of 564.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
Deduct 4945 from 5509 and we're left with 564.
Take the next digit (9) from the dividend and append it to 564, then repeat: 5649 / 989

On to step 7:
989 can be fit into 5649 5 times, resulting in a remainder of 704.
Use 5 as the next digit of our solution. 
Result so far: 2555.0
If we take 4945 away from 5649, we end up with 704.
Include the next digit (3) from the dividend after 704, then repeat: 7043 / 989

Advancing to step 8:
7043 divided by 989 is 7 with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 25557.0
If we subtract 6923 from 7043, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 9:
1200 divided by 989 is 1 with a remainder of 211.
The next digit of our result is 1. 
Result so far: 25557.1
Subtract 989 from 1200 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 10:
989 can be fit into 2110 2 times, resulting in a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 25557.12
If we take 1978 away from 2110, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
If we divide 1320 by 989, we get 1 and a remainder of 331.
Put 1 as the next digit of the answer. 
Result so far: 25557.121
If we subtract 989 from 1320, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 12:
If we divide 3310 by 989, we get 3 and a remainder of 343.
Write down 3 as next digit of the result. 
Result so far: 25557.1213
Subtracting 2967 from 3310 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 13:
The number 989 fits into 3430 3 times, leaving a remainder of 463.
Record the quotient 3 as the next digit in the result. 
Result so far: 25557.12133
Subtract 2967 from 3430 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

The final result is 25557.12133 with a remainder of 0.000463.
