We look at the division of 37376426 by 428 
The aim is to understand the frequency of 428 in 37376426.

Going ahead to step 1:
The number 428 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 428

On to step 2:
If we divide 37 by 428, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 428

Step 3:
373 divided by 428 is 0 with a remainder of 373.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 373, we end up with 373.
Include the next digit (7) from the dividend after 373, then repeat: 3737 / 428

Step 4:
The number 428 fits into 3737 8 times, leaving a remainder of 313.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 3424 from 3737 leaves us with 313.
Append the next digit (6) from the dividend to 313 and continue with: 3136 / 428

Let's proceed to step 5:
428 can be fit into 3136 7 times, resulting in a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 140 after subtracting 2996 from 3136.
Fetch the next digit (4) from the dividend, attach it to 140 and continue: 1404 / 428

Let's proceed to step 6:
When dividing 1404 by 428, we get 3 with a remainder of 120.
The next digit of our result is 3. 
Result so far: 873.0
The remainder is 120 after subtracting 1284 from 1404.
Grab the next digit (2) from the dividend, add it to 120, then carry on: 1202 / 428

Going ahead to step 7:
428 goes into 1202 2 times with a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 8732.0
Deduct 856 from 1202 and we're left with 346.
Take the next digit (6) from the dividend and append it to 346, then repeat: 3466 / 428

Let's proceed to step 8:
428 can be fit into 3466 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 87328.0
Subtracting 3424 from 3466 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
The number 428 fits into 420 0 times, leaving a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 87328.0
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
4200 divided by 428 is 9 with a remainder of 348.
Write down 9 as next digit of the result. 
Result so far: 87328.09
Deduct 3852 from 4200 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 11:
428 can be fit into 3480 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 87328.098
Subtract 3424 from 3480 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
When dividing 560 by 428, we get 1 with a remainder of 132.
The next digit of our result is 1. 
Result so far: 87328.0981
Deduct 428 from 560 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
When dividing 1320 by 428, we get 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 87328.09813
Deduct 1284 from 1320 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.

Going ahead to step 14:
The number 428 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 87328.09813
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 15:
3600 divided by 428 is 8 with a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 87328.0981308
Subtract 3424 from 3600 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 16:
428 goes into 1760 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 87328.09813084
Subtract 1712 from 1760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 87328.09813084 with a balance of 4.8e-08.
