We look at the division of 37429154 by 400 
The aim is to understand the frequency of 400 in 37429154.

Advancing to step 1:
400 can be fit into 3 0 times, resulting in 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.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 400

Step 2:
400 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 400

Let's proceed to step 3:
When dividing 374 by 400, we get 0 with a remainder of 374.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 374 after subtracting 0 from 374.
Grab the next digit (2) from the dividend, add it to 374, then carry on: 3742 / 400

Moving on to step 4:
3742 divided by 400 is 9 with a remainder of 142.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 3600 from 3742 leaves us with 142.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 400

Moving on to step 5:
If we divide 1429 by 400, we get 3 and a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtracting 1200 from 1429 leaves us with 229.
Take the next digit (1) from the dividend and append it to 229, then repeat: 2291 / 400

Moving on to step 6:
When dividing 2291 by 400, we get 5 with a remainder of 291.
The next digit of our result is 5. 
Result so far: 935.0
Deduct 2000 from 2291 and we're left with 291.
Include the next digit (5) from the dividend after 291, then repeat: 2915 / 400

Let's proceed to step 7:
400 can be fit into 2915 7 times, resulting in a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 9357.0
Subtract 2800 from 2915 to get 115.
Grab the next digit (4) from the dividend, add it to 115, then carry on: 1154 / 400

On to step 8:
If we divide 1154 by 400, we get 2 and a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 93572.0
The remainder is 354 after subtracting 800 from 1154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 9:
When dividing 3540 by 400, we get 8 with a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 93572.8
If we take 3200 away from 3540, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
If we divide 3400 by 400, we get 8 and a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 93572.88
If we take 3200 away from 3400, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 93572.88, and the remainder is 0.2.
