We look at the division of 25890086 by 706 
We want to divide 25890086 by 706.

Advancing to step 1:
2 divided by 706 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 706

Step 2:
706 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 706

Let's proceed to step 3:
If we divide 258 by 706, we get 0 and a remainder of 258.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 258 to get 258.
Bring next digit (9) of the dividend behind the 258 and repeat the process: 2589 / 706

Let's proceed to step 4:
The number 706 fits into 2589 3 times, leaving a remainder of 471.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2118 from 2589 to get 471.
Bring next digit (0) of the dividend behind the 471 and repeat the process: 4710 / 706

Advancing to step 5:
If we divide 4710 by 706, we get 6 and a remainder of 474.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 4236 from 4710 leaves us with 474.
Fetch the next digit (0) from the dividend, attach it to 474 and continue: 4740 / 706

Let's proceed to step 6:
4740 divided by 706 is 6 with a remainder of 504.
The number 6 becomes the next digit in our result. 
Result so far: 366.0
Subtracting 4236 from 4740 leaves us with 504.
Append the next digit (8) from the dividend to 504 and continue with: 5048 / 706

Advancing to step 7:
When dividing 5048 by 706, we get 7 with a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 3667.0
The remainder is 106 after subtracting 4942 from 5048.
Take the next digit (6) from the dividend and append it to 106, then repeat: 1066 / 706

On to step 8:
The number 706 fits into 1066 1 times, leaving a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 36671.0
Deduct 706 from 1066 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.

Moving on to step 9:
When dividing 3600 by 706, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 36671.5
If we subtract 3530 from 3600, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
The number 706 fits into 700 0 times, leaving a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 36671.5
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
706 can be fit into 7000 9 times, resulting in a remainder of 646.
Write down 9 as next digit of the result. 
Result so far: 36671.509
Subtract 6354 from 7000 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Advancing to step 12:
706 goes into 6460 9 times with a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 36671.5099
The remainder is 106 after subtracting 6354 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final outcome is 36671.5099, with a leftover of 0.00106.
