53525646 ÷ 169 
The aim is to understand the frequency of 169 in 53525646.

On to step 1:
If we divide 5 by 169, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 169

Advancing to step 2:
The number 169 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 169

Moving on to step 3:
When dividing 535 by 169, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 507 from 535, we get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 169

Let's proceed to step 4:
169 can be fit into 282 1 times, resulting in a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 169 away from 282, we end up with 113.
Include the next digit (5) from the dividend after 113, then repeat: 1135 / 169

On to step 5:
169 can be fit into 1135 6 times, resulting in a remainder of 121.
Put 6 as the next digit of the answer. 
Result so far: 316.0
Deduct 1014 from 1135 and we're left with 121.
Grab the next digit (6) from the dividend, add it to 121, then carry on: 1216 / 169

Step 6:
1216 divided by 169 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 3167.0
Deduct 1183 from 1216 and we're left with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 169

Going ahead to step 7:
If we divide 334 by 169, we get 1 and a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 31671.0
If we take 169 away from 334, we end up with 165.
Take the next digit (6) from the dividend and append it to 165, then repeat: 1656 / 169

Let's proceed to step 8:
169 can be fit into 1656 9 times, resulting in a remainder of 135.
Put 9 as the next digit of the answer. 
Result so far: 316719.0
Subtract 1521 from 1656 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 9:
1350 divided by 169 is 7 with a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 316719.7
Subtracting 1183 from 1350 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 10:
If we divide 1670 by 169, we get 9 and a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 316719.79
If we take 1521 away from 1670, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 11:
1490 divided by 169 is 8 with a remainder of 138.
The next digit of our result is 8. 
Result so far: 316719.798
Subtracting 1352 from 1490 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 12:
169 goes into 1380 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 316719.7988
The remainder is 28 after subtracting 1352 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 316719.7988, and the remainder is 0.00028.
