69729389 divided by 402 
Our goal is to divide 69729389 by 402.

Going ahead to step 1:
If we divide 6 by 402, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 402

Advancing to step 2:
402 can be fit into 69 0 times, resulting in a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 402

Step 3:
402 can be fit into 697 1 times, resulting in a remainder of 295.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 402 away from 697, we end up with 295.
Include the next digit (2) from the dividend after 295, then repeat: 2952 / 402

Step 4:
If we divide 2952 by 402, we get 7 and a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 2814 from 2952 and we're left with 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 402

Let's proceed to step 5:
402 goes into 1389 3 times with a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Deduct 1206 from 1389 and we're left with 183.
Append the next digit (3) from the dividend to 183 and continue with: 1833 / 402

On to step 6:
402 can be fit into 1833 4 times, resulting in a remainder of 225.
The next digit of our result is 4. 
Result so far: 1734.0
Subtract 1608 from 1833 to get 225.
Take the next digit (8) from the dividend and append it to 225, then repeat: 2258 / 402

Step 7:
402 goes into 2258 5 times with a remainder of 248.
Record the quotient 5 as the next digit in the result. 
Result so far: 17345.0
The remainder is 248 after subtracting 2010 from 2258.
Grab the next digit (9) from the dividend, add it to 248, then carry on: 2489 / 402

Let's proceed to step 8:
The number 402 fits into 2489 6 times, leaving a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 173456.0
Subtracting 2412 from 2489 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
The number 402 fits into 770 1 times, leaving a remainder of 368.
Put 1 as the next digit of the answer. 
Result so far: 173456.1
If we take 402 away from 770, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 10:
402 goes into 3680 9 times with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 173456.19
Subtracting 3618 from 3680 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
The number 402 fits into 620 1 times, leaving a remainder of 218.
Write down 1 as next digit of the result. 
Result so far: 173456.191
Subtracting 402 from 620 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 12:
When dividing 2180 by 402, we get 5 with a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 173456.1915
If we subtract 2010 from 2180, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
402 can be fit into 1700 4 times, resulting in a remainder of 92.
The next digit of our result is 4. 
Result so far: 173456.19154
If we take 1608 away from 1700, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
920 divided by 402 is 2 with a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 173456.191542
Subtract 804 from 920 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 15:
1160 divided by 402 is 2 with a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 173456.1915422
Subtracting 804 from 1160 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final outcome is 173456.1915422, with a leftover of 3.56e-06.
