Let's divide 69308955 by 646
We're looking to find how many times 646 goes into 69308955.

Step 1:
646 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 646

Let's proceed to step 2:
If we divide 69 by 646, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 646

Advancing to step 3:
If we divide 693 by 646, we get 1 and a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 646 from 693 and we're left with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 646

Advancing to step 4:
When dividing 470 by 646, we get 0 with a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 470, we get 470.
Include the next digit (8) from the dividend after 470, then repeat: 4708 / 646

Step 5:
646 can be fit into 4708 7 times, resulting in a remainder of 186.
The next digit of our result is 7. 
Result so far: 107.0
If we subtract 4522 from 4708, we get 186.
Fetch the next digit (9) from the dividend, attach it to 186 and continue: 1869 / 646

On to step 6:
When dividing 1869 by 646, we get 2 with a remainder of 577.
Put 2 as the next digit of the answer. 
Result so far: 1072.0
If we subtract 1292 from 1869, we get 577.
Fetch the next digit (5) from the dividend, attach it to 577 and continue: 5775 / 646

On to step 7:
646 can be fit into 5775 8 times, resulting in a remainder of 607.
Record the quotient 8 as the next digit in the result. 
Result so far: 10728.0
If we take 5168 away from 5775, we end up with 607.
Grab the next digit (5) from the dividend, add it to 607, then carry on: 6075 / 646

On to step 8:
6075 divided by 646 is 9 with a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 107289.0
If we subtract 5814 from 6075, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 9:
646 can be fit into 2610 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 107289.4
If we subtract 2584 from 2610, 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.

Advancing to step 10:
260 divided by 646 is 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 107289.4
Subtracting 0 from 260 leaves us 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.

Moving on to step 11:
646 can be fit into 2600 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 107289.404
If we take 2584 away from 2600, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 646 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 107289.404
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
If we divide 1600 by 646, we get 2 and a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 107289.40402
Subtract 1292 from 1600 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 14:
If we divide 3080 by 646, we get 4 and a remainder of 496.
Put 4 as the next digit of the answer. 
Result so far: 107289.404024
If we subtract 2584 from 3080, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 15:
4960 divided by 646 is 7 with a remainder of 438.
The next digit of our result is 7. 
Result so far: 107289.4040247
Subtracting 4522 from 4960 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 16:
If we divide 4380 by 646, we get 6 and a remainder of 504.
The next digit of our result is 6. 
Result so far: 107289.40402476
If we subtract 3876 from 4380, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

In conclusion, the division gives 107289.40402476 with a balance of 5.04e-07.
