We divide 23390523 by 690
Our goal is to divide 23390523 by 690.

On to step 1:
690 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
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 690

Advancing to step 2:
23 divided by 690 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 690

Going ahead to step 3:
690 can be fit into 233 0 times, resulting in a remainder of 233.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 233 leaves us with 233.
Append the next digit (9) from the dividend to 233 and continue with: 2339 / 690

On to step 4:
The number 690 fits into 2339 3 times, leaving a remainder of 269.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 269 after subtracting 2070 from 2339.
Fetch the next digit (0) from the dividend, attach it to 269 and continue: 2690 / 690

Moving on to step 5:
690 goes into 2690 3 times with a remainder of 620.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 2070 from 2690 leaves us with 620.
Fetch the next digit (5) from the dividend, attach it to 620 and continue: 6205 / 690

Going ahead to step 6:
690 can be fit into 6205 8 times, resulting in a remainder of 685.
Put 8 as the next digit of the answer. 
Result so far: 338.0
The remainder is 685 after subtracting 5520 from 6205.
Take the next digit (2) from the dividend and append it to 685, then repeat: 6852 / 690

Step 7:
690 can be fit into 6852 9 times, resulting in a remainder of 642.
Write down 9 as next digit of the result. 
Result so far: 3389.0
Subtract 6210 from 6852 to get 642.
Grab the next digit (3) from the dividend, add it to 642, then carry on: 6423 / 690

On to step 8:
690 goes into 6423 9 times with a remainder of 213.
Put 9 as the next digit of the answer. 
Result so far: 33899.0
If we take 6210 away from 6423, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 9:
690 can be fit into 2130 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 33899.3
Deduct 2070 from 2130 and we're left 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.

Moving on to step 10:
600 divided by 690 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 33899.3
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
If we divide 6000 by 690, we get 8 and a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 33899.308
Subtracting 5520 from 6000 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
If we divide 4800 by 690, we get 6 and a remainder of 660.
Record the quotient 6 as the next digit in the result. 
Result so far: 33899.3086
Deduct 4140 from 4800 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 13:
If we divide 6600 by 690, we get 9 and a remainder of 390.
The next digit of our result is 9. 
Result so far: 33899.30869
If we subtract 6210 from 6600, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 14:
690 goes into 3900 5 times with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 33899.308695
Deduct 3450 from 3900 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 15:
If we divide 4500 by 690, we get 6 and a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 33899.3086956
Subtracting 4140 from 4500 leaves us 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.

Moving on to step 16:
3600 divided by 690 is 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 33899.30869565
Subtract 3450 from 3600 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 33899.30869565, with a leftover of 1.5e-07.
