Let's divide 49809232 by 690
The aim is to understand the frequency of 690 in 49809232.

On to step 1:
690 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 690

Step 2:
49 divided by 690 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 690

Going ahead to step 3:
690 goes into 498 0 times with a remainder of 498.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 498, we end up with 498.
Grab the next digit (0) from the dividend, add it to 498, then carry on: 4980 / 690

Step 4:
The number 690 fits into 4980 7 times, leaving a remainder of 150.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4830 from 4980, we get 150.
Fetch the next digit (9) from the dividend, attach it to 150 and continue: 1509 / 690

Going ahead to step 5:
690 can be fit into 1509 2 times, resulting in a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 1380 from 1509 and we're left with 129.
Append the next digit (2) from the dividend to 129 and continue with: 1292 / 690

Let's proceed to step 6:
If we divide 1292 by 690, we get 1 and a remainder of 602.
The next digit of our result is 1. 
Result so far: 721.0
Subtract 690 from 1292 to get 602.
Fetch the next digit (3) from the dividend, attach it to 602 and continue: 6023 / 690

Advancing to step 7:
6023 divided by 690 is 8 with a remainder of 503.
Write down 8 as next digit of the result. 
Result so far: 7218.0
Deduct 5520 from 6023 and we're left with 503.
Bring next digit (2) of the dividend behind the 503 and repeat the process: 5032 / 690

Advancing to step 8:
When dividing 5032 by 690, we get 7 with a remainder of 202.
Record the quotient 7 as the next digit in the result. 
Result so far: 72187.0
Subtracting 4830 from 5032 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 9:
When dividing 2020 by 690, we get 2 with a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 72187.2
If we subtract 1380 from 2020, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
690 can be fit into 6400 9 times, resulting in a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 72187.29
The remainder is 190 after subtracting 6210 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
If we divide 1900 by 690, we get 2 and a remainder of 520.
Record the quotient 2 as the next digit in the result. 
Result so far: 72187.292
Subtracting 1380 from 1900 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 12:
The number 690 fits into 5200 7 times, leaving a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 72187.2927
Subtracting 4830 from 5200 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 13:
3700 divided by 690 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 72187.29275
Deduct 3450 from 3700 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 14:
690 goes into 2500 3 times with a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 72187.292753
Subtract 2070 from 2500 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 15:
690 can be fit into 4300 6 times, resulting in a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 72187.2927536
The remainder is 160 after subtracting 4140 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
690 goes into 1600 2 times with a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 72187.29275362
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.

The final outcome is 72187.29275362, with a leftover of 2.2e-07.
