7156946 ÷ 402 
The aim is to understand the frequency of 402 in 7156946.

On to step 1:
When dividing 7 by 402, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 402

Let's proceed to step 2:
402 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 402

Step 3:
715 divided by 402 is 1 with a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 402 from 715 and we're left with 313.
Fetch the next digit (6) from the dividend, attach it to 313 and continue: 3136 / 402

On to step 4:
The number 402 fits into 3136 7 times, leaving a remainder of 322.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 2814 from 3136 leaves us with 322.
Bring next digit (9) of the dividend behind the 322 and repeat the process: 3229 / 402

Step 5:
3229 divided by 402 is 8 with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 178.0
If we take 3216 away from 3229, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 402

Let's proceed to step 6:
If we divide 134 by 402, we get 0 and a remainder of 134.
Use 0 as the next digit of our solution. 
Result so far: 1780.0
If we subtract 0 from 134, we get 134.
Include the next digit (6) from the dividend after 134, then repeat: 1346 / 402

Let's proceed to step 7:
If we divide 1346 by 402, we get 3 and a remainder of 140.
The next digit of our result is 3. 
Result so far: 17803.0
Deduct 1206 from 1346 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 8:
The number 402 fits into 1400 3 times, leaving a remainder of 194.
Use 3 as the next digit of our solution. 
Result so far: 17803.3
If we subtract 1206 from 1400, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 9:
402 goes into 1940 4 times with a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 17803.34
If we take 1608 away from 1940, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
If we divide 3320 by 402, we get 8 and a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 17803.348
If we take 3216 away from 3320, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
When dividing 1040 by 402, we get 2 with a remainder of 236.
Write down 2 as next digit of the result. 
Result so far: 17803.3482
If we subtract 804 from 1040, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 12:
402 goes into 2360 5 times with a remainder of 350.
The next digit of our result is 5. 
Result so far: 17803.34825
Subtracting 2010 from 2360 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
When dividing 3500 by 402, we get 8 with a remainder of 284.
Write down 8 as next digit of the result. 
Result so far: 17803.348258
If we take 3216 away from 3500, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 14:
402 can be fit into 2840 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 17803.3482587
If we subtract 2814 from 2840, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 15:
The number 402 fits into 260 0 times, leaving a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 17803.3482587
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 17803.3482587 with a remaining 2.6e-07.
