37480610 divided by 420 
The aim is to understand the frequency of 420 in 37480610.

Advancing to step 1:
The number 420 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 420

Moving on to step 2:
37 divided by 420 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 420

On to step 3:
The number 420 fits into 374 0 times, leaving a remainder of 374.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 374, we end up with 374.
Fetch the next digit (8) from the dividend, attach it to 374 and continue: 3748 / 420

Going ahead to step 4:
420 goes into 3748 8 times with a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 3360 from 3748 and we're left with 388.
Bring next digit (0) of the dividend behind the 388 and repeat the process: 3880 / 420

Let's proceed to step 5:
When dividing 3880 by 420, we get 9 with a remainder of 100.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 3780 from 3880, we get 100.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 420

Step 6:
1006 divided by 420 is 2 with a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 892.0
If we subtract 840 from 1006, we get 166.
Include the next digit (1) from the dividend after 166, then repeat: 1661 / 420

Step 7:
420 goes into 1661 3 times with a remainder of 401.
Record the quotient 3 as the next digit in the result. 
Result so far: 8923.0
Subtracting 1260 from 1661 leaves us with 401.
Include the next digit (0) from the dividend after 401, then repeat: 4010 / 420

Let's proceed to step 8:
420 goes into 4010 9 times with a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 89239.0
The remainder is 230 after subtracting 3780 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
If we divide 2300 by 420, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 89239.5
Subtract 2100 from 2300 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 89239.54
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
420 goes into 3200 7 times with a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 89239.547
If we subtract 2940 from 3200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
The number 420 fits into 2600 6 times, leaving a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 89239.5476
Subtracting 2520 from 2600 leaves us with 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 420, we get 1 and a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 89239.54761
If we take 420 away from 800, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 14:
If we divide 3800 by 420, we get 9 and a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 89239.547619
The remainder is 20 after subtracting 3780 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
When dividing 200 by 420, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 89239.547619
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
The next digit of our result is 4. 
Result so far: 89239.54761904
Deduct 1680 from 2000 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 89239.54761904 with a remainder of 3.2e-07.
