We're dividing 13988808 by 670 
We want to divide 13988808 by 670.

On to step 1:
1 divided by 670 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 670

Let's proceed to step 2:
If we divide 13 by 670, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 670

On to step 3:
139 divided by 670 is 0 with a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Grab the next digit (8) from the dividend, add it to 139, then carry on: 1398 / 670

Let's proceed to step 4:
When dividing 1398 by 670, we get 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1340 away from 1398, we end up with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 670

On to step 5:
670 goes into 588 0 times with a remainder of 588.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 588 after subtracting 0 from 588.
Append the next digit (8) from the dividend to 588 and continue with: 5888 / 670

Moving on to step 6:
When dividing 5888 by 670, we get 8 with a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 208.0
Subtract 5360 from 5888 to get 528.
Grab the next digit (0) from the dividend, add it to 528, then carry on: 5280 / 670

Going ahead to step 7:
670 can be fit into 5280 7 times, resulting in a remainder of 590.
Write down 7 as next digit of the result. 
Result so far: 2087.0
If we subtract 4690 from 5280, we get 590.
Include the next digit (8) from the dividend after 590, then repeat: 5908 / 670

Step 8:
If we divide 5908 by 670, we get 8 and a remainder of 548.
The next digit of our result is 8. 
Result so far: 20878.0
Subtract 5360 from 5908 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 9:
The number 670 fits into 5480 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 20878.8
Subtract 5360 from 5480 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
When dividing 1200 by 670, we get 1 with a remainder of 530.
Record the quotient 1 as the next digit in the result. 
Result so far: 20878.81
The remainder is 530 after subtracting 670 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 11:
If we divide 5300 by 670, we get 7 and a remainder of 610.
Record the quotient 7 as the next digit in the result. 
Result so far: 20878.817
The remainder is 610 after subtracting 4690 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 12:
6100 divided by 670 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 20878.8179
Subtract 6030 from 6100 to 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.

Let's proceed to step 13:
When dividing 700 by 670, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 20878.81791
If we take 670 away from 700, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
If we divide 300 by 670, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 20878.81791
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
When dividing 3000 by 670, we get 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 20878.8179104
If we subtract 2680 from 3000, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
The number 670 fits into 3200 4 times, leaving a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 20878.81791044
Subtract 2680 from 3200 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

In conclusion, the division gives 20878.81791044 with a balance of 5.2e-07.
