51669806 ÷ 673 
The aim is to understand the frequency of 673 in 51669806.

Going ahead to step 1:
673 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 673

Let's proceed to step 2:
If we divide 51 by 673, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 673

Step 3:
If we divide 516 by 673, we get 0 and a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 516 after subtracting 0 from 516.
Grab the next digit (6) from the dividend, add it to 516, then carry on: 5166 / 673

Let's proceed to step 4:
5166 divided by 673 is 7 with a remainder of 455.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4711 away from 5166, we end up with 455.
Include the next digit (9) from the dividend after 455, then repeat: 4559 / 673

Let's proceed to step 5:
If we divide 4559 by 673, we get 6 and a remainder of 521.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 4038 from 4559, we get 521.
Append the next digit (8) from the dividend to 521 and continue with: 5218 / 673

Step 6:
If we divide 5218 by 673, we get 7 and a remainder of 507.
Put 7 as the next digit of the answer. 
Result so far: 767.0
If we take 4711 away from 5218, we end up with 507.
Fetch the next digit (0) from the dividend, attach it to 507 and continue: 5070 / 673

Step 7:
673 can be fit into 5070 7 times, resulting in a remainder of 359.
Record the quotient 7 as the next digit in the result. 
Result so far: 7677.0
Deduct 4711 from 5070 and we're left with 359.
Take the next digit (6) from the dividend and append it to 359, then repeat: 3596 / 673

Step 8:
When dividing 3596 by 673, we get 5 with a remainder of 231.
The next digit of our result is 5. 
Result so far: 76775.0
Deduct 3365 from 3596 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

On to step 9:
If we divide 2310 by 673, we get 3 and a remainder of 291.
Write down 3 as next digit of the result. 
Result so far: 76775.3
If we subtract 2019 from 2310, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 10:
When dividing 2910 by 673, we get 4 with a remainder of 218.
Record the quotient 4 as the next digit in the result. 
Result so far: 76775.34
If we subtract 2692 from 2910, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 11:
When dividing 2180 by 673, we get 3 with a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 76775.343
Subtracting 2019 from 2180 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 12:
673 goes into 1610 2 times with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 76775.3432
The remainder is 264 after subtracting 1346 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 13:
673 can be fit into 2640 3 times, resulting in a remainder of 621.
Record the quotient 3 as the next digit in the result. 
Result so far: 76775.34323
Subtract 2019 from 2640 to get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 14:
If we divide 6210 by 673, we get 9 and a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 76775.343239
If we subtract 6057 from 6210, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 15:
673 can be fit into 1530 2 times, resulting in a remainder of 184.
The next digit of our result is 2. 
Result so far: 76775.3432392
Subtract 1346 from 1530 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 16:
673 goes into 1840 2 times with a remainder of 494.
Write down 2 as next digit of the result. 
Result so far: 76775.34323922
Deduct 1346 from 1840 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

In conclusion, the division gives 76775.34323922 with a balance of 4.94e-07.
