We divide 37663700 by 429
The aim is to understand the frequency of 429 in 37663700.

Advancing to step 1:
If we divide 3 by 429, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 429

Step 2:
When dividing 37 by 429, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 429

On to step 3:
The number 429 fits into 376 0 times, leaving a remainder of 376.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 376 leaves us with 376.
Bring next digit (6) of the dividend behind the 376 and repeat the process: 3766 / 429

Advancing to step 4:
429 goes into 3766 8 times with a remainder of 334.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 3432 away from 3766, we end up with 334.
Bring next digit (3) of the dividend behind the 334 and repeat the process: 3343 / 429

Moving on to step 5:
3343 divided by 429 is 7 with a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 3003 from 3343, we get 340.
Bring next digit (7) of the dividend behind the 340 and repeat the process: 3407 / 429

Let's proceed to step 6:
The number 429 fits into 3407 7 times, leaving a remainder of 404.
Write down 7 as next digit of the result. 
Result so far: 877.0
The remainder is 404 after subtracting 3003 from 3407.
Bring next digit (0) of the dividend behind the 404 and repeat the process: 4040 / 429

Let's proceed to step 7:
429 goes into 4040 9 times with a remainder of 179.
Record the quotient 9 as the next digit in the result. 
Result so far: 8779.0
The remainder is 179 after subtracting 3861 from 4040.
Include the next digit (0) from the dividend after 179, then repeat: 1790 / 429

Let's proceed to step 8:
When dividing 1790 by 429, we get 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 87794.0
The remainder is 74 after subtracting 1716 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
429 goes into 740 1 times with a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 87794.1
Subtract 429 from 740 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 10:
The number 429 fits into 3110 7 times, leaving a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 87794.17
Subtracting 3003 from 3110 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 11:
If we divide 1070 by 429, we get 2 and a remainder of 212.
The next digit of our result is 2. 
Result so far: 87794.172
If we subtract 858 from 1070, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 12:
2120 divided by 429 is 4 with a remainder of 404.
The next digit of our result is 4. 
Result so far: 87794.1724
Subtracting 1716 from 2120 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 13:
If we divide 4040 by 429, we get 9 and a remainder of 179.
The number 9 becomes the next digit in our result. 
Result so far: 87794.17249
If we take 3861 away from 4040, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 14:
429 goes into 1790 4 times with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 87794.172494
If we take 1716 away from 1790, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 15:
When dividing 740 by 429, we get 1 with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 87794.1724941
If we subtract 429 from 740, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 16:
429 can be fit into 3110 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 87794.17249417
Subtract 3003 from 3110 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 87794.17249417 with a remainder of 1.07e-07.
