69721148 ÷ 343 
We want to figure out the number of times 69721148 can be divided by 343.

Let's proceed to step 1:
The number 343 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 343

On to step 2:
69 divided by 343 is 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 343

Let's proceed to step 3:
The number 343 fits into 697 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 686 from 697 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 343

Advancing to step 4:
343 can be fit into 112 0 times, resulting in a remainder of 112.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 112 to get 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 343

Moving on to step 5:
If we divide 1121 by 343, we get 3 and a remainder of 92.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Deduct 1029 from 1121 and we're left with 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 343

On to step 6:
When dividing 921 by 343, we get 2 with a remainder of 235.
Write down 2 as next digit of the result. 
Result so far: 2032.0
If we subtract 686 from 921, we get 235.
Append the next digit (4) from the dividend to 235 and continue with: 2354 / 343

Moving on to step 7:
343 can be fit into 2354 6 times, resulting in a remainder of 296.
The next digit of our result is 6. 
Result so far: 20326.0
Deduct 2058 from 2354 and we're left with 296.
Bring next digit (8) of the dividend behind the 296 and repeat the process: 2968 / 343

Moving on to step 8:
343 goes into 2968 8 times with a remainder of 224.
The next digit of our result is 8. 
Result so far: 203268.0
Subtract 2744 from 2968 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 9:
The number 343 fits into 2240 6 times, leaving a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 203268.6
The remainder is 182 after subtracting 2058 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 10:
343 goes into 1820 5 times with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 203268.65
If we subtract 1715 from 1820, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 11:
The number 343 fits into 1050 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 203268.653
If we take 1029 away from 1050, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
The number 343 fits into 210 0 times, leaving a remainder of 210.
The next digit of our result is 0. 
Result so far: 203268.653
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 13:
When dividing 2100 by 343, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 203268.65306
The remainder is 42 after subtracting 2058 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
420 divided by 343 is 1 with a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 203268.653061
If we take 343 away from 420, we end up 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.

Advancing to step 15:
If we divide 770 by 343, we get 2 and a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 203268.6530612
Deduct 686 from 770 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 16:
343 can be fit into 840 2 times, resulting in a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 203268.65306122
Subtracting 686 from 840 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 203268.65306122 with a balance of 1.54e-07.
