We divide 25385867 by 490
We want to figure out the number of times 25385867 can be divided by 490.

Going ahead to step 1:
2 divided by 490 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 490

On to step 2:
If we divide 25 by 490, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 490

Step 3:
When dividing 253 by 490, we get 0 with a remainder of 253.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 253 and we're left with 253.
Fetch the next digit (8) from the dividend, attach it to 253 and continue: 2538 / 490

Advancing to step 4:
The number 490 fits into 2538 5 times, leaving a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2450 from 2538 to get 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 490

Advancing to step 5:
490 goes into 885 1 times with a remainder of 395.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtracting 490 from 885 leaves us with 395.
Take the next digit (8) from the dividend and append it to 395, then repeat: 3958 / 490

Moving on to step 6:
If we divide 3958 by 490, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 518.0
Subtracting 3920 from 3958 leaves us with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 490

Advancing to step 7:
When dividing 386 by 490, we get 0 with a remainder of 386.
Use 0 as the next digit of our solution. 
Result so far: 5180.0
The remainder is 386 after subtracting 0 from 386.
Fetch the next digit (7) from the dividend, attach it to 386 and continue: 3867 / 490

On to step 8:
3867 divided by 490 is 7 with a remainder of 437.
The next digit of our result is 7. 
Result so far: 51807.0
The remainder is 437 after subtracting 3430 from 3867.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 9:
The number 490 fits into 4370 8 times, leaving a remainder of 450.
Put 8 as the next digit of the answer. 
Result so far: 51807.8
Subtract 3920 from 4370 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
When dividing 4500 by 490, we get 9 with a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 51807.89
Subtracting 4410 from 4500 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
If we divide 900 by 490, we get 1 and a remainder of 410.
The next digit of our result is 1. 
Result so far: 51807.891
Subtracting 490 from 900 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 12:
490 can be fit into 4100 8 times, resulting in a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 51807.8918
The remainder is 180 after subtracting 3920 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
490 can be fit into 1800 3 times, resulting in a remainder of 330.
The number 3 becomes the next digit in our result. 
Result so far: 51807.89183
Subtracting 1470 from 1800 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
3300 divided by 490 is 6 with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 51807.891836
Deduct 2940 from 3300 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 15:
490 goes into 3600 7 times with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 51807.8918367
Subtract 3430 from 3600 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 16:
490 goes into 1700 3 times with a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 51807.89183673
Subtracting 1470 from 1700 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Our division results in 51807.89183673 with a remaining 2.3e-07.
