We look at the division of 12899090 by 606 
Our goal is to divide 12899090 by 606.

Advancing to step 1:
606 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 606

Let's proceed to step 2:
When dividing 12 by 606, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 606

Advancing to step 3:
The number 606 fits into 128 0 times, leaving a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 606

Moving on to step 4:
606 goes into 1289 2 times with a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1212 from 1289, we get 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 606

Advancing to step 5:
606 can be fit into 779 1 times, resulting in a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 606 from 779 leaves us with 173.
Append the next digit (0) from the dividend to 173 and continue with: 1730 / 606

Moving on to step 6:
606 can be fit into 1730 2 times, resulting in a remainder of 518.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
If we take 1212 away from 1730, we end up with 518.
Take the next digit (9) from the dividend and append it to 518, then repeat: 5189 / 606

Advancing to step 7:
606 can be fit into 5189 8 times, resulting in a remainder of 341.
Write down 8 as next digit of the result. 
Result so far: 2128.0
Subtracting 4848 from 5189 leaves us with 341.
Include the next digit (0) from the dividend after 341, then repeat: 3410 / 606

Let's proceed to step 8:
3410 divided by 606 is 5 with a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 21285.0
The remainder is 380 after subtracting 3030 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
606 can be fit into 3800 6 times, resulting in a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 21285.6
If we subtract 3636 from 3800, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
1640 divided by 606 is 2 with a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 21285.62
If we subtract 1212 from 1640, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 11:
The number 606 fits into 4280 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 21285.627
Deduct 4242 from 4280 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
606 can be fit into 380 0 times, resulting in a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 21285.627
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 13:
When dividing 3800 by 606, we get 6 with a remainder of 164.
The next digit of our result is 6. 
Result so far: 21285.62706
If we take 3636 away from 3800, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 14:
The number 606 fits into 1640 2 times, leaving a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 21285.627062
Subtract 1212 from 1640 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 15:
If we divide 4280 by 606, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 21285.6270627
If we take 4242 away from 4280, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 16:
606 can be fit into 380 0 times, resulting in a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 21285.6270627
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 21285.6270627 with a remainder of 3.8e-07.
