25265985 divided by 486 
Our goal is to divide 25265985 by 486.

Going ahead to step 1:
The number 486 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 486

Moving on to step 2:
If we divide 25 by 486, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 486

Going ahead to step 3:
The number 486 fits into 252 0 times, leaving a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 252 to get 252.
Bring next digit (6) of the dividend behind the 252 and repeat the process: 2526 / 486

Advancing to step 4:
When dividing 2526 by 486, we get 5 with a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 2430 from 2526 and we're left with 96.
Include the next digit (5) from the dividend after 96, then repeat: 965 / 486

Advancing to step 5:
The number 486 fits into 965 1 times, leaving a remainder of 479.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 486 from 965 leaves us with 479.
Fetch the next digit (9) from the dividend, attach it to 479 and continue: 4799 / 486

Let's proceed to step 6:
The number 486 fits into 4799 9 times, leaving a remainder of 425.
Write down 9 as next digit of the result. 
Result so far: 519.0
If we subtract 4374 from 4799, we get 425.
Fetch the next digit (8) from the dividend, attach it to 425 and continue: 4258 / 486

Let's proceed to step 7:
486 goes into 4258 8 times with a remainder of 370.
Record the quotient 8 as the next digit in the result. 
Result so far: 5198.0
If we subtract 3888 from 4258, we get 370.
Take the next digit (5) from the dividend and append it to 370, then repeat: 3705 / 486

Going ahead to step 8:
The number 486 fits into 3705 7 times, leaving a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 51987.0
The remainder is 303 after subtracting 3402 from 3705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 9:
486 can be fit into 3030 6 times, resulting in a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 51987.6
Subtracting 2916 from 3030 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
486 can be fit into 1140 2 times, resulting in a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 51987.62
Subtracting 972 from 1140 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 11:
486 goes into 1680 3 times with a remainder of 222.
Record the quotient 3 as the next digit in the result. 
Result so far: 51987.623
Deduct 1458 from 1680 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 12:
When dividing 2220 by 486, we get 4 with a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 51987.6234
If we subtract 1944 from 2220, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 13:
When dividing 2760 by 486, we get 5 with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 51987.62345
Deduct 2430 from 2760 and we're left 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:
If we divide 3300 by 486, we get 6 and a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 51987.623456
Subtract 2916 from 3300 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 15:
486 can be fit into 3840 7 times, resulting in a remainder of 438.
Record the quotient 7 as the next digit in the result. 
Result so far: 51987.6234567
Subtract 3402 from 3840 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 16:
When dividing 4380 by 486, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 51987.62345679
Subtracting 4374 from 4380 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 51987.62345679, with a leftover of 6e-09.
