6539948 ÷ 169 
The aim is to understand the frequency of 169 in 6539948.

Let's proceed to step 1:
When dividing 6 by 169, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 169

Let's proceed to step 2:
169 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 169

On to step 3:
653 divided by 169 is 3 with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 507 away from 653, we end up with 146.
Append the next digit (9) from the dividend to 146 and continue with: 1469 / 169

On to step 4:
169 can be fit into 1469 8 times, resulting in a remainder of 117.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 1352 from 1469, we get 117.
Fetch the next digit (9) from the dividend, attach it to 117 and continue: 1179 / 169

Let's proceed to step 5:
169 goes into 1179 6 times with a remainder of 165.
The next digit of our result is 6. 
Result so far: 386.0
Deduct 1014 from 1179 and we're left with 165.
Grab the next digit (4) from the dividend, add it to 165, then carry on: 1654 / 169

Moving on to step 6:
The number 169 fits into 1654 9 times, leaving a remainder of 133.
Use 9 as the next digit of our solution. 
Result so far: 3869.0
Subtracting 1521 from 1654 leaves us with 133.
Include the next digit (8) from the dividend after 133, then repeat: 1338 / 169

Step 7:
When dividing 1338 by 169, we get 7 with a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 38697.0
Subtract 1183 from 1338 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 8:
1550 divided by 169 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 38697.9
If we take 1521 away from 1550, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
The number 169 fits into 290 1 times, leaving a remainder of 121.
The number 1 becomes the next digit in our result. 
Result so far: 38697.91
Deduct 169 from 290 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 10:
169 goes into 1210 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 38697.917
Deduct 1183 from 1210 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
When dividing 270 by 169, we get 1 with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 38697.9171
If we subtract 169 from 270, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 12:
169 can be fit into 1010 5 times, resulting in a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 38697.91715
Deduct 845 from 1010 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 13:
1650 divided by 169 is 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 38697.917159
The remainder is 129 after subtracting 1521 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 14:
1290 divided by 169 is 7 with a remainder of 107.
Record the quotient 7 as the next digit in the result. 
Result so far: 38697.9171597
The remainder is 107 after subtracting 1183 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 15:
1070 divided by 169 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 38697.91715976
Subtracting 1014 from 1070 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 38697.91715976, and the remainder is 5.6e-08.
