We're dividing 25131129 by 806 
We want to divide 25131129 by 806.

On to step 1:
806 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 806

Let's proceed to step 2:
When dividing 25 by 806, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 806

On to step 3:
If we divide 251 by 806, we get 0 and a remainder of 251.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 251, we end up with 251.
Append the next digit (3) from the dividend to 251 and continue with: 2513 / 806

Let's proceed to step 4:
When dividing 2513 by 806, we get 3 with a remainder of 95.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2418 from 2513 to get 95.
Bring next digit (1) of the dividend behind the 95 and repeat the process: 951 / 806

Step 5:
951 divided by 806 is 1 with a remainder of 145.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 806 from 951 leaves us with 145.
Append the next digit (1) from the dividend to 145 and continue with: 1451 / 806

Moving on to step 6:
If we divide 1451 by 806, we get 1 and a remainder of 645.
Put 1 as the next digit of the answer. 
Result so far: 311.0
Subtracting 806 from 1451 leaves us with 645.
Append the next digit (2) from the dividend to 645 and continue with: 6452 / 806

Step 7:
If we divide 6452 by 806, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 3118.0
Subtracting 6448 from 6452 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 806

On to step 8:
The number 806 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 31180.0
Subtract 0 from 49 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
The number 806 fits into 490 0 times, leaving a remainder of 490.
Use 0 as the next digit of our solution. 
Result so far: 31180.0
Subtracting 0 from 490 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
806 can be fit into 4900 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 31180.06
Subtracting 4836 from 4900 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 806, we get 0 and a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 31180.06
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 12:
806 goes into 6400 7 times with a remainder of 758.
Write down 7 as next digit of the result. 
Result so far: 31180.0607
Subtracting 5642 from 6400 leaves us with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Going ahead to step 13:
806 can be fit into 7580 9 times, resulting in a remainder of 326.
Put 9 as the next digit of the answer. 
Result so far: 31180.06079
The remainder is 326 after subtracting 7254 from 7580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 14:
806 goes into 3260 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 31180.060794
Deduct 3224 from 3260 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
The number 806 fits into 360 0 times, leaving a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 31180.060794
If we take 0 away from 360, we end up 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.

Step 16:
806 goes into 3600 4 times with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 31180.06079404
The remainder is 376 after subtracting 3224 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

After the division, we end up with 31180.06079404 and a remainder of 3.76e-07.
