14166690 ÷ 690 
Our goal is to divide 14166690 by 690.

Step 1:
The number 690 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 690

Moving on to step 2:
The number 690 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 690

Moving on to step 3:
141 divided by 690 is 0 with a remainder of 141.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 141, we get 141.
Fetch the next digit (6) from the dividend, attach it to 141 and continue: 1416 / 690

Advancing to step 4:
1416 divided by 690 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1380 from 1416, we get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 690

Let's proceed to step 5:
690 can be fit into 366 0 times, resulting in a remainder of 366.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 366, we end up with 366.
Include the next digit (6) from the dividend after 366, then repeat: 3666 / 690

On to step 6:
690 goes into 3666 5 times with a remainder of 216.
Write down 5 as next digit of the result. 
Result so far: 205.0
Deduct 3450 from 3666 and we're left with 216.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 690

Let's proceed to step 7:
If we divide 2169 by 690, we get 3 and a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 2053.0
Subtract 2070 from 2169 to get 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 690

On to step 8:
690 goes into 990 1 times with a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 20531.0
Subtracting 690 from 990 leaves us 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.

Step 9:
The number 690 fits into 3000 4 times, leaving a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 20531.4
The remainder is 240 after subtracting 2760 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
690 can be fit into 2400 3 times, resulting in a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 20531.43
Deduct 2070 from 2400 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.

Moving on to step 11:
690 can be fit into 3300 4 times, resulting in a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 20531.434
The remainder is 540 after subtracting 2760 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 12:
The number 690 fits into 5400 7 times, leaving a remainder of 570.
Write down 7 as next digit of the result. 
Result so far: 20531.4347
If we subtract 4830 from 5400, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 13:
If we divide 5700 by 690, we get 8 and a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 20531.43478
Subtract 5520 from 5700 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
If we divide 1800 by 690, we get 2 and a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 20531.434782
If we take 1380 away from 1800, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
690 can be fit into 4200 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 20531.4347826
If we take 4140 away from 4200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
600 divided by 690 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 20531.4347826
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 20531.4347826 with a remaining 6e-07.
