69121547 ÷ 402 
Let's see how many times 402 fits into 69121547.

On to step 1:
If we divide 6 by 402, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 402

Step 2:
402 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 402

Advancing to step 3:
402 can be fit into 691 1 times, resulting in a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 402 from 691 and we're left with 289.
Fetch the next digit (2) from the dividend, attach it to 289 and continue: 2892 / 402

Advancing to step 4:
If we divide 2892 by 402, we get 7 and a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 78 after subtracting 2814 from 2892.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 402

On to step 5:
402 goes into 781 1 times with a remainder of 379.
Write down 1 as next digit of the result. 
Result so far: 171.0
If we take 402 away from 781, we end up with 379.
Include the next digit (5) from the dividend after 379, then repeat: 3795 / 402

Advancing to step 6:
The number 402 fits into 3795 9 times, leaving a remainder of 177.
Record the quotient 9 as the next digit in the result. 
Result so far: 1719.0
The remainder is 177 after subtracting 3618 from 3795.
Append the next digit (4) from the dividend to 177 and continue with: 1774 / 402

Going ahead to step 7:
When dividing 1774 by 402, we get 4 with a remainder of 166.
The number 4 becomes the next digit in our result. 
Result so far: 17194.0
If we take 1608 away from 1774, we end up with 166.
Include the next digit (7) from the dividend after 166, then repeat: 1667 / 402

On to step 8:
When dividing 1667 by 402, we get 4 with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 171944.0
The remainder is 59 after subtracting 1608 from 1667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
402 can be fit into 590 1 times, resulting in a remainder of 188.
The next digit of our result is 1. 
Result so far: 171944.1
Deduct 402 from 590 and we're left 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.

Let's proceed to step 10:
402 can be fit into 1880 4 times, resulting in a remainder of 272.
The number 4 becomes the next digit in our result. 
Result so far: 171944.14
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.

Let's proceed to step 11:
402 goes into 2720 6 times with a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 171944.146
Deduct 2412 from 2720 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 12:
The number 402 fits into 3080 7 times, leaving a remainder of 266.
The number 7 becomes the next digit in our result. 
Result so far: 171944.1467
Subtracting 2814 from 3080 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 13:
2660 divided by 402 is 6 with a remainder of 248.
The next digit of our result is 6. 
Result so far: 171944.14676
The remainder is 248 after subtracting 2412 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 14:
The number 402 fits into 2480 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 171944.146766
Deduct 2412 from 2480 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 171944.146766, and the remainder is 6.8e-06.
