We look at the division of 59484755 by 400 
The aim is to understand the frequency of 400 in 59484755.

Let's proceed to step 1:
400 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
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 400

Step 2:
400 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 400

Advancing to step 3:
400 goes into 594 1 times with a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 400 away from 594, we end up with 194.
Append the next digit (8) from the dividend to 194 and continue with: 1948 / 400

Let's proceed to step 4:
When dividing 1948 by 400, we get 4 with a remainder of 348.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 1600 from 1948, we get 348.
Include the next digit (4) from the dividend after 348, then repeat: 3484 / 400

Step 5:
The number 400 fits into 3484 8 times, leaving a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Deduct 3200 from 3484 and we're left with 284.
Bring next digit (7) of the dividend behind the 284 and repeat the process: 2847 / 400

Advancing to step 6:
400 goes into 2847 7 times with a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 1487.0
Deduct 2800 from 2847 and we're left with 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 400

Step 7:
The number 400 fits into 475 1 times, leaving a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 14871.0
If we subtract 400 from 475, we get 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 400

Advancing to step 8:
The number 400 fits into 755 1 times, leaving a remainder of 355.
The number 1 becomes the next digit in our result. 
Result so far: 148711.0
If we take 400 away from 755, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 9:
400 can be fit into 3550 8 times, resulting in a remainder of 350.
Use 8 as the next digit of our solution. 
Result so far: 148711.8
Subtract 3200 from 3550 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
400 can be fit into 3500 8 times, resulting in a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 148711.88
The remainder is 300 after subtracting 3200 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 148711.88, and the remainder is 0.3.
