53509983 ÷ 672 
The aim is to understand the frequency of 672 in 53509983.

On to step 1:
If we divide 5 by 672, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 672

Moving on to step 2:
If we divide 53 by 672, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 672

Step 3:
672 goes into 535 0 times with a remainder of 535.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 535, we end up with 535.
Append the next digit (0) from the dividend to 535 and continue with: 5350 / 672

On to step 4:
672 goes into 5350 7 times with a remainder of 646.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 646 after subtracting 4704 from 5350.
Include the next digit (9) from the dividend after 646, then repeat: 6469 / 672

Advancing to step 5:
The number 672 fits into 6469 9 times, leaving a remainder of 421.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 6048 from 6469 leaves us with 421.
Take the next digit (9) from the dividend and append it to 421, then repeat: 4219 / 672

Step 6:
672 goes into 4219 6 times with a remainder of 187.
Put 6 as the next digit of the answer. 
Result so far: 796.0
Deduct 4032 from 4219 and we're left with 187.
Append the next digit (8) from the dividend to 187 and continue with: 1878 / 672

Going ahead to step 7:
The number 672 fits into 1878 2 times, leaving a remainder of 534.
Use 2 as the next digit of our solution. 
Result so far: 7962.0
If we subtract 1344 from 1878, we get 534.
Fetch the next digit (3) from the dividend, attach it to 534 and continue: 5343 / 672

Let's proceed to step 8:
672 can be fit into 5343 7 times, resulting in a remainder of 639.
The number 7 becomes the next digit in our result. 
Result so far: 79627.0
The remainder is 639 after subtracting 4704 from 5343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 9:
672 can be fit into 6390 9 times, resulting in a remainder of 342.
Put 9 as the next digit of the answer. 
Result so far: 79627.9
Subtract 6048 from 6390 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 10:
If we divide 3420 by 672, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 79627.95
Deduct 3360 from 3420 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
672 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 79627.95
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 12:
If we divide 6000 by 672, we get 8 and a remainder of 624.
Use 8 as the next digit of our solution. 
Result so far: 79627.9508
If we subtract 5376 from 6000, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 13:
672 goes into 6240 9 times with a remainder of 192.
The next digit of our result is 9. 
Result so far: 79627.95089
Subtracting 6048 from 6240 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
The number 672 fits into 1920 2 times, leaving a remainder of 576.
The number 2 becomes the next digit in our result. 
Result so far: 79627.950892
Subtracting 1344 from 1920 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 15:
When dividing 5760 by 672, we get 8 with a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 79627.9508928
The remainder is 384 after subtracting 5376 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 16:
3840 divided by 672 is 5 with a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 79627.95089285
If we take 3360 away from 3840, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 79627.95089285, and the remainder is 4.8e-07.
