53945364 ÷ 873 
The aim is to understand the frequency of 873 in 53945364.

On to step 1:
873 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 873

Going ahead to step 2:
The number 873 fits into 53 0 times, leaving a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 873

On to step 3:
When dividing 539 by 873, we get 0 with a remainder of 539.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 539 to get 539.
Include the next digit (4) from the dividend after 539, then repeat: 5394 / 873

On to step 4:
873 goes into 5394 6 times with a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5238 away from 5394, we end up with 156.
Include the next digit (5) from the dividend after 156, then repeat: 1565 / 873

Advancing to step 5:
1565 divided by 873 is 1 with a remainder of 692.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Subtracting 873 from 1565 leaves us with 692.
Include the next digit (3) from the dividend after 692, then repeat: 6923 / 873

Let's proceed to step 6:
When dividing 6923 by 873, we get 7 with a remainder of 812.
The next digit of our result is 7. 
Result so far: 617.0
If we take 6111 away from 6923, we end up with 812.
Fetch the next digit (6) from the dividend, attach it to 812 and continue: 8126 / 873

Let's proceed to step 7:
8126 divided by 873 is 9 with a remainder of 269.
The number 9 becomes the next digit in our result. 
Result so far: 6179.0
If we take 7857 away from 8126, we end up with 269.
Take the next digit (4) from the dividend and append it to 269, then repeat: 2694 / 873

Step 8:
2694 divided by 873 is 3 with a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 61793.0
Deduct 2619 from 2694 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
750 divided by 873 is 0 with a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 61793.0
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 10:
When dividing 7500 by 873, we get 8 with a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 61793.08
If we take 6984 away from 7500, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 11:
When dividing 5160 by 873, we get 5 with a remainder of 795.
The number 5 becomes the next digit in our result. 
Result so far: 61793.085
Subtracting 4365 from 5160 leaves us with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Advancing to step 12:
The number 873 fits into 7950 9 times, leaving a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 61793.0859
Deduct 7857 from 7950 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 13:
The number 873 fits into 930 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 61793.08591
If we subtract 873 from 930, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 14:
873 can be fit into 570 0 times, resulting in a remainder of 570.
Use 0 as the next digit of our solution. 
Result so far: 61793.08591
Deduct 0 from 570 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 15:
If we divide 5700 by 873, we get 6 and a remainder of 462.
Record the quotient 6 as the next digit in the result. 
Result so far: 61793.0859106
Deduct 5238 from 5700 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 16:
If we divide 4620 by 873, we get 5 and a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 61793.08591065
If we subtract 4365 from 4620, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

In conclusion, the division gives 61793.08591065 with a balance of 2.55e-07.
