48693639 ÷ 690 
We're looking to find how many times 690 goes into 48693639.

On to step 1:
When dividing 4 by 690, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 690

On to step 2:
690 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 690

Going ahead to step 3:
When dividing 486 by 690, we get 0 with a remainder of 486.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 486 to get 486.
Include the next digit (9) from the dividend after 486, then repeat: 4869 / 690

On to step 4:
When dividing 4869 by 690, we get 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 4830 from 4869 leaves us with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 690

Moving on to step 5:
690 goes into 393 0 times with a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 393 leaves us with 393.
Fetch the next digit (6) from the dividend, attach it to 393 and continue: 3936 / 690

Going ahead to step 6:
If we divide 3936 by 690, we get 5 and a remainder of 486.
Put 5 as the next digit of the answer. 
Result so far: 705.0
If we subtract 3450 from 3936, we get 486.
Grab the next digit (3) from the dividend, add it to 486, then carry on: 4863 / 690

Moving on to step 7:
When dividing 4863 by 690, we get 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 7057.0
If we take 4830 away from 4863, we end up with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 690

Moving on to step 8:
690 can be fit into 339 0 times, resulting in a remainder of 339.
Put 0 as the next digit of the answer. 
Result so far: 70570.0
Subtract 0 from 339 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 9:
3390 divided by 690 is 4 with a remainder of 630.
Use 4 as the next digit of our solution. 
Result so far: 70570.4
If we take 2760 away from 3390, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
690 goes into 6300 9 times with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 70570.49
If we subtract 6210 from 6300, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
690 goes into 900 1 times with a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 70570.491
The remainder is 210 after subtracting 690 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 12:
The number 690 fits into 2100 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 70570.4913
Subtract 2070 from 2100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
If we divide 300 by 690, we get 0 and a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 70570.4913
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 14:
690 can be fit into 3000 4 times, resulting in a remainder of 240.
The next digit of our result is 4. 
Result so far: 70570.491304
Subtract 2760 from 3000 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
If we divide 2400 by 690, we get 3 and a remainder of 330.
Put 3 as the next digit of the answer. 
Result so far: 70570.4913043
If we take 2070 away from 2400, we end up 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.

On to step 16:
The number 690 fits into 3300 4 times, leaving a remainder of 540.
The number 4 becomes the next digit in our result. 
Result so far: 70570.49130434
If we subtract 2760 from 3300, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final result is 70570.49130434 with a remainder of 5.4e-07.
