53557721 ÷ 978 
The aim is to understand the frequency of 978 in 53557721.

Advancing to step 1:
978 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 978

Going ahead to step 2:
53 divided by 978 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 978

Going ahead to step 3:
978 can be fit into 535 0 times, resulting in a remainder of 535.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 535, we get 535.
Fetch the next digit (5) from the dividend, attach it to 535 and continue: 5355 / 978

On to step 4:
5355 divided by 978 is 5 with a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4890 from 5355 to get 465.
Fetch the next digit (7) from the dividend, attach it to 465 and continue: 4657 / 978

Going ahead to step 5:
978 can be fit into 4657 4 times, resulting in a remainder of 745.
The next digit of our result is 4. 
Result so far: 54.0
Deduct 3912 from 4657 and we're left with 745.
Fetch the next digit (7) from the dividend, attach it to 745 and continue: 7457 / 978

Step 6:
978 goes into 7457 7 times with a remainder of 611.
The next digit of our result is 7. 
Result so far: 547.0
If we take 6846 away from 7457, we end up with 611.
Grab the next digit (2) from the dividend, add it to 611, then carry on: 6112 / 978

Moving on to step 7:
6112 divided by 978 is 6 with a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 5476.0
The remainder is 244 after subtracting 5868 from 6112.
Take the next digit (1) from the dividend and append it to 244, then repeat: 2441 / 978

Advancing to step 8:
If we divide 2441 by 978, we get 2 and a remainder of 485.
Record the quotient 2 as the next digit in the result. 
Result so far: 54762.0
The remainder is 485 after subtracting 1956 from 2441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 9:
4850 divided by 978 is 4 with a remainder of 938.
Put 4 as the next digit of the answer. 
Result so far: 54762.4
If we take 3912 away from 4850, we end up with 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

Going ahead to step 10:
If we divide 9380 by 978, we get 9 and a remainder of 578.
The number 9 becomes the next digit in our result. 
Result so far: 54762.49
Subtract 8802 from 9380 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 11:
978 can be fit into 5780 5 times, resulting in a remainder of 890.
Use 5 as the next digit of our solution. 
Result so far: 54762.495
If we take 4890 away from 5780, we end up with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Step 12:
If we divide 8900 by 978, we get 9 and a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 54762.4959
The remainder is 98 after subtracting 8802 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 13:
980 divided by 978 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 54762.49591
The remainder is 2 after subtracting 978 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
When dividing 20 by 978, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 54762.49591
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
200 divided by 978 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 54762.49591
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 54762.49591 with a balance of 2e-06.
