3633978 ÷ 357 
The aim is to understand the frequency of 357 in 3633978.

Let's proceed to step 1:
When dividing 3 by 357, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 357

Let's proceed to step 2:
357 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 357

Step 3:
357 can be fit into 363 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 357 from 363 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 357

Going ahead to step 4:
357 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 357

Going ahead to step 5:
639 divided by 357 is 1 with a remainder of 282.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 282 after subtracting 357 from 639.
Fetch the next digit (7) from the dividend, attach it to 282 and continue: 2827 / 357

Advancing to step 6:
When dividing 2827 by 357, we get 7 with a remainder of 328.
Use 7 as the next digit of our solution. 
Result so far: 1017.0
Deduct 2499 from 2827 and we're left with 328.
Grab the next digit (8) from the dividend, add it to 328, then carry on: 3288 / 357

Let's proceed to step 7:
357 can be fit into 3288 9 times, resulting in a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 10179.0
The remainder is 75 after subtracting 3213 from 3288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
When dividing 750 by 357, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 10179.2
Deduct 714 from 750 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 357 fits into 360 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 10179.21
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
30 divided by 357 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10179.21
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 357 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 10179.21
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 10179.21 with a balance of 0.003.
