We're dividing 66428139 by 341 
We want to divide 66428139 by 341.

Moving on to step 1:
When dividing 6 by 341, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 341

Step 2:
66 divided by 341 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 341

Moving on to step 3:
664 divided by 341 is 1 with a remainder of 323.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 341 from 664 to get 323.
Fetch the next digit (2) from the dividend, attach it to 323 and continue: 3232 / 341

Advancing to step 4:
The number 341 fits into 3232 9 times, leaving a remainder of 163.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 3069 from 3232 and we're left with 163.
Grab the next digit (8) from the dividend, add it to 163, then carry on: 1638 / 341

Step 5:
The number 341 fits into 1638 4 times, leaving a remainder of 274.
The next digit of our result is 4. 
Result so far: 194.0
Deduct 1364 from 1638 and we're left with 274.
Fetch the next digit (1) from the dividend, attach it to 274 and continue: 2741 / 341

Going ahead to step 6:
341 can be fit into 2741 8 times, resulting in a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 1948.0
If we take 2728 away from 2741, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 341

On to step 7:
133 divided by 341 is 0 with a remainder of 133.
The next digit of our result is 0. 
Result so far: 19480.0
Subtract 0 from 133 to get 133.
Append the next digit (9) from the dividend to 133 and continue with: 1339 / 341

On to step 8:
341 goes into 1339 3 times with a remainder of 316.
Put 3 as the next digit of the answer. 
Result so far: 194803.0
If we take 1023 away from 1339, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 9:
3160 divided by 341 is 9 with a remainder of 91.
The next digit of our result is 9. 
Result so far: 194803.9
Deduct 3069 from 3160 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
If we divide 910 by 341, we get 2 and a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 194803.92
Subtracting 682 from 910 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
The number 341 fits into 2280 6 times, leaving a remainder of 234.
The next digit of our result is 6. 
Result so far: 194803.926
If we take 2046 away from 2280, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 12:
The number 341 fits into 2340 6 times, leaving a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 194803.9266
The remainder is 294 after subtracting 2046 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Our division results in 194803.9266 with a remaining 0.00294.
