We divide 30051400 by 402
The aim is to understand the frequency of 402 in 30051400.

On to step 1:
When dividing 3 by 402, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 402

Let's proceed to step 2:
402 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 402

Step 3:
The number 402 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 300, we get 300.
Take the next digit (5) from the dividend and append it to 300, then repeat: 3005 / 402

Advancing to step 4:
3005 divided by 402 is 7 with a remainder of 191.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 191 after subtracting 2814 from 3005.
Grab the next digit (1) from the dividend, add it to 191, then carry on: 1911 / 402

Step 5:
The number 402 fits into 1911 4 times, leaving a remainder of 303.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 1608 away from 1911, we end up with 303.
Bring next digit (4) of the dividend behind the 303 and repeat the process: 3034 / 402

Advancing to step 6:
The number 402 fits into 3034 7 times, leaving a remainder of 220.
Use 7 as the next digit of our solution. 
Result so far: 747.0
The remainder is 220 after subtracting 2814 from 3034.
Grab the next digit (0) from the dividend, add it to 220, then carry on: 2200 / 402

On to step 7:
402 can be fit into 2200 5 times, resulting in a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 7475.0
If we subtract 2010 from 2200, we get 190.
Bring next digit (0) of the dividend behind the 190 and repeat the process: 1900 / 402

On to step 8:
When dividing 1900 by 402, we get 4 with a remainder of 292.
Write down 4 as next digit of the result. 
Result so far: 74754.0
If we take 1608 away from 1900, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 9:
2920 divided by 402 is 7 with a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 74754.7
If we subtract 2814 from 2920, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
402 can be fit into 1060 2 times, resulting in a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 74754.72
Subtracting 804 from 1060 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
402 goes into 2560 6 times with a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 74754.726
If we subtract 2412 from 2560, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 12:
If we divide 1480 by 402, we get 3 and a remainder of 274.
Put 3 as the next digit of the answer. 
Result so far: 74754.7263
The remainder is 274 after subtracting 1206 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 13:
The number 402 fits into 2740 6 times, leaving a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 74754.72636
Subtracting 2412 from 2740 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 14:
If we divide 3280 by 402, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 74754.726368
If we subtract 3216 from 3280, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
640 divided by 402 is 1 with a remainder of 238.
The next digit of our result is 1. 
Result so far: 74754.7263681
Deduct 402 from 640 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 16:
When dividing 2380 by 402, we get 5 with a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 74754.72636815
Subtracting 2010 from 2380 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 74754.72636815, with a leftover of 3.7e-07.
