Let's divide 83704952 by 690
The aim is to understand the frequency of 690 in 83704952.

Moving on to step 1:
If we divide 8 by 690, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 690

Moving on to step 2:
The number 690 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 690

Let's proceed to step 3:
837 divided by 690 is 1 with a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 690 from 837 to get 147.
Include the next digit (0) from the dividend after 147, then repeat: 1470 / 690

Let's proceed to step 4:
690 can be fit into 1470 2 times, resulting in a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1380 away from 1470, we end up with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 690

Step 5:
The number 690 fits into 904 1 times, leaving a remainder of 214.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 690 from 904 to get 214.
Bring next digit (9) of the dividend behind the 214 and repeat the process: 2149 / 690

Moving on to step 6:
690 goes into 2149 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 1213.0
If we take 2070 away from 2149, we end up with 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 690

Let's proceed to step 7:
690 goes into 795 1 times with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 12131.0
If we take 690 away from 795, we end up with 105.
Append the next digit (2) from the dividend to 105 and continue with: 1052 / 690

On to step 8:
When dividing 1052 by 690, we get 1 with a remainder of 362.
Record the quotient 1 as the next digit in the result. 
Result so far: 121311.0
Deduct 690 from 1052 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 9:
When dividing 3620 by 690, we get 5 with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 121311.5
If we subtract 3450 from 3620, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
When dividing 1700 by 690, we get 2 with a remainder of 320.
The next digit of our result is 2. 
Result so far: 121311.52
Deduct 1380 from 1700 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 11:
The number 690 fits into 3200 4 times, leaving a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 121311.524
If we take 2760 away from 3200, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
690 goes into 4400 6 times with a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 121311.5246
The remainder is 260 after subtracting 4140 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
If we divide 2600 by 690, we get 3 and a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 121311.52463
Subtract 2070 from 2600 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 14:
If we divide 5300 by 690, we get 7 and a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 121311.524637
Deduct 4830 from 5300 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 15:
If we divide 4700 by 690, we get 6 and a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 121311.5246376
If we subtract 4140 from 4700, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 16:
The number 690 fits into 5600 8 times, leaving a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 121311.52463768
Subtract 5520 from 5600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 121311.52463768 with a remainder of 8e-08.
