Let's see how many times 690 fits into 39909781.

Advancing to step 1:
3 divided by 690 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 690

Going ahead to step 2:
When dividing 39 by 690, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 690

Moving on to step 3:
690 can be fit into 399 0 times, resulting in a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 399 leaves us with 399.
Take the next digit (0) from the dividend and append it to 399, then repeat: 3990 / 690

Advancing to step 4:
3990 divided by 690 is 5 with a remainder of 540.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3450 from 3990 and we're left with 540.
Take the next digit (9) from the dividend and append it to 540, then repeat: 5409 / 690

On to step 5:
When dividing 5409 by 690, we get 7 with a remainder of 579.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 579 after subtracting 4830 from 5409.
Include the next digit (7) from the dividend after 579, then repeat: 5797 / 690

On to step 6:
The number 690 fits into 5797 8 times, leaving a remainder of 277.
The next digit of our result is 8. 
Result so far: 578.0
Subtracting 5520 from 5797 leaves us with 277.
Grab the next digit (8) from the dividend, add it to 277, then carry on: 2778 / 690

Advancing to step 7:
When dividing 2778 by 690, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 5784.0
If we take 2760 away from 2778, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 690

Let's proceed to step 8:
690 can be fit into 181 0 times, resulting in a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 57840.0
If we subtract 0 from 181, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
If we divide 1810 by 690, we get 2 and a remainder of 430.
Write down 2 as next digit of the result. 
Result so far: 57840.2
The remainder is 430 after subtracting 1380 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 10:
4300 divided by 690 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 57840.26
If we subtract 4140 from 4300, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
690 goes into 1600 2 times with a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 57840.262
Subtract 1380 from 1600 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
If we divide 2200 by 690, we get 3 and a remainder of 130.
The next digit of our result is 3. 
Result so far: 57840.2623
If we take 2070 away from 2200, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 13:
690 can be fit into 1300 1 times, resulting in a remainder of 610.
Use 1 as the next digit of our solution. 
Result so far: 57840.26231
Deduct 690 from 1300 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 14:
The number 690 fits into 6100 8 times, leaving a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 57840.262318
The remainder is 580 after subtracting 5520 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 15:
If we divide 5800 by 690, we get 8 and a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 57840.2623188
The remainder is 280 after subtracting 5520 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 57840.2623188, with a leftover of 2.8e-06.
