68642636 divided by 402 
Our goal is to divide 68642636 by 402.

Moving on to step 1:
402 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 402

Let's proceed to step 2:
68 divided by 402 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 402

Moving on to step 3:
686 divided by 402 is 1 with a remainder of 284.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 402 from 686 leaves us with 284.
Include the next digit (4) from the dividend after 284, then repeat: 2844 / 402

Let's proceed to step 4:
The number 402 fits into 2844 7 times, leaving a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 2814 from 2844, we get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 402

Moving on to step 5:
402 can be fit into 302 0 times, resulting in a remainder of 302.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we take 0 away from 302, we end up with 302.
Take the next digit (6) from the dividend and append it to 302, then repeat: 3026 / 402

Step 6:
When dividing 3026 by 402, we get 7 with a remainder of 212.
The next digit of our result is 7. 
Result so far: 1707.0
If we take 2814 away from 3026, we end up with 212.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 402

Going ahead to step 7:
402 goes into 2123 5 times with a remainder of 113.
Write down 5 as next digit of the result. 
Result so far: 17075.0
If we take 2010 away from 2123, we end up with 113.
Bring next digit (6) of the dividend behind the 113 and repeat the process: 1136 / 402

Let's proceed to step 8:
402 can be fit into 1136 2 times, resulting in a remainder of 332.
The next digit of our result is 2. 
Result so far: 170752.0
The remainder is 332 after subtracting 804 from 1136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 9:
The number 402 fits into 3320 8 times, leaving a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 170752.8
Subtracting 3216 from 3320 leaves us 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.

Step 10:
If we divide 1040 by 402, we get 2 and a remainder of 236.
Use 2 as the next digit of our solution. 
Result so far: 170752.82
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.

Advancing to step 11:
When dividing 2360 by 402, we get 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 170752.825
If we subtract 2010 from 2360, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
402 can be fit into 3500 8 times, resulting in a remainder of 284.
The next digit of our result is 8. 
Result so far: 170752.8258
Subtracting 3216 from 3500 leaves us 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.

Going ahead to step 13:
When dividing 2840 by 402, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 170752.82587
The remainder is 26 after subtracting 2814 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
The number 402 fits into 260 0 times, leaving a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 170752.82587
Subtract 0 from 260 to 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.

Moving on to step 15:
When dividing 2600 by 402, we get 6 with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 170752.8258706
Subtracting 2412 from 2600 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 16:
402 can be fit into 1880 4 times, resulting in a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 170752.82587064
Subtract 1608 from 1880 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

In conclusion, the division gives 170752.82587064 with a balance of 2.72e-07.
