We're dividing 99473735 by 438 
The aim is to understand the frequency of 438 in 99473735.

Going ahead to step 1:
The number 438 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 438

Let's proceed to step 2:
438 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (4) from the dividend, add it to 99, then carry on: 994 / 438

Advancing to step 3:
994 divided by 438 is 2 with a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 876 from 994 and we're left with 118.
Include the next digit (7) from the dividend after 118, then repeat: 1187 / 438

Advancing to step 4:
The number 438 fits into 1187 2 times, leaving a remainder of 311.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 876 away from 1187, we end up with 311.
Take the next digit (3) from the dividend and append it to 311, then repeat: 3113 / 438

Step 5:
438 can be fit into 3113 7 times, resulting in a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 227.0
Deduct 3066 from 3113 and we're left with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 438

Moving on to step 6:
If we divide 477 by 438, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 2271.0
If we subtract 438 from 477, we get 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 438

Let's proceed to step 7:
If we divide 393 by 438, we get 0 and a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 22710.0
Subtract 0 from 393 to get 393.
Grab the next digit (5) from the dividend, add it to 393, then carry on: 3935 / 438

Going ahead to step 8:
If we divide 3935 by 438, we get 8 and a remainder of 431.
Write down 8 as next digit of the result. 
Result so far: 227108.0
Subtract 3504 from 3935 to get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Moving on to step 9:
438 can be fit into 4310 9 times, resulting in a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 227108.9
Subtract 3942 from 4310 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 10:
438 goes into 3680 8 times with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 227108.98
The remainder is 176 after subtracting 3504 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 11:
438 can be fit into 1760 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 227108.984
The remainder is 8 after subtracting 1752 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
438 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 227108.984
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
If we divide 800 by 438, we get 1 and a remainder of 362.
Write down 1 as next digit of the result. 
Result so far: 227108.98401
Subtract 438 from 800 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 14:
438 can be fit into 3620 8 times, resulting in a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 227108.984018
If we subtract 3504 from 3620, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 15:
438 goes into 1160 2 times with a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 227108.9840182
The remainder is 284 after subtracting 876 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 16:
438 goes into 2840 6 times with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 227108.98401826
If we take 2628 away from 2840, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 227108.98401826, and the remainder is 2.12e-07.
