66558342 ÷ 380 
We want to figure out the number of times 66558342 can be divided by 380.

Advancing to step 1:
380 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 380

Going ahead to step 2:
The number 380 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 380

Advancing to step 3:
380 can be fit into 665 1 times, resulting in a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 380 from 665, we get 285.
Grab the next digit (5) from the dividend, add it to 285, then carry on: 2855 / 380

Advancing to step 4:
380 can be fit into 2855 7 times, resulting in a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 2660 from 2855, we get 195.
Take the next digit (8) from the dividend and append it to 195, then repeat: 1958 / 380

Going ahead to step 5:
1958 divided by 380 is 5 with a remainder of 58.
The next digit of our result is 5. 
Result so far: 175.0
Subtract 1900 from 1958 to get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 380

Step 6:
583 divided by 380 is 1 with a remainder of 203.
The next digit of our result is 1. 
Result so far: 1751.0
Deduct 380 from 583 and we're left with 203.
Fetch the next digit (4) from the dividend, attach it to 203 and continue: 2034 / 380

Step 7:
380 can be fit into 2034 5 times, resulting in a remainder of 134.
Put 5 as the next digit of the answer. 
Result so far: 17515.0
If we subtract 1900 from 2034, we get 134.
Bring next digit (2) of the dividend behind the 134 and repeat the process: 1342 / 380

Advancing to step 8:
1342 divided by 380 is 3 with a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 175153.0
The remainder is 202 after subtracting 1140 from 1342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 9:
2020 divided by 380 is 5 with a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 175153.5
Subtract 1900 from 2020 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
If we divide 1200 by 380, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 175153.53
The remainder is 60 after subtracting 1140 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
600 divided by 380 is 1 with a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 175153.531
Subtract 380 from 600 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
When dividing 2200 by 380, we get 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 175153.5315
If we subtract 1900 from 2200, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
380 goes into 3000 7 times with a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 175153.53157
Deduct 2660 from 3000 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
If we divide 3400 by 380, we get 8 and a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 175153.531578
Subtracting 3040 from 3400 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
If we divide 3600 by 380, we get 9 and a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 175153.5315789
Subtracting 3420 from 3600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
380 can be fit into 1800 4 times, resulting in a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 175153.53157894
The remainder is 280 after subtracting 1520 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 175153.53157894, with a leftover of 2.8e-07.
