55691073 ÷ 343 
We want to divide 55691073 by 343.

Step 1:
The number 343 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 343

Step 2:
343 goes into 55 0 times with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 343

On to step 3:
When dividing 556 by 343, we get 1 with a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 343 from 556 leaves us with 213.
Grab the next digit (9) from the dividend, add it to 213, then carry on: 2139 / 343

Going ahead to step 4:
343 goes into 2139 6 times with a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 81 after subtracting 2058 from 2139.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 343

Let's proceed to step 5:
When dividing 811 by 343, we get 2 with a remainder of 125.
The next digit of our result is 2. 
Result so far: 162.0
If we subtract 686 from 811, we get 125.
Take the next digit (0) from the dividend and append it to 125, then repeat: 1250 / 343

Let's proceed to step 6:
1250 divided by 343 is 3 with a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 1623.0
If we subtract 1029 from 1250, we get 221.
Append the next digit (7) from the dividend to 221 and continue with: 2217 / 343

Moving on to step 7:
2217 divided by 343 is 6 with a remainder of 159.
The number 6 becomes the next digit in our result. 
Result so far: 16236.0
Subtract 2058 from 2217 to get 159.
Bring next digit (3) of the dividend behind the 159 and repeat the process: 1593 / 343

On to step 8:
If we divide 1593 by 343, we get 4 and a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 162364.0
Deduct 1372 from 1593 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 9:
2210 divided by 343 is 6 with a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 162364.6
Subtracting 2058 from 2210 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
If we divide 1520 by 343, we get 4 and a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 162364.64
Deduct 1372 from 1520 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 11:
If we divide 1480 by 343, we get 4 and a remainder of 108.
The next digit of our result is 4. 
Result so far: 162364.644
Subtracting 1372 from 1480 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Our division results in 162364.644 with a remaining 0.0108.
