We look at the division of 66874180 by 388 
We want to figure out the number of times 66874180 can be divided by 388.

On to step 1:
388 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 388

Step 2:
66 divided by 388 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 388

Let's proceed to step 3:
The number 388 fits into 668 1 times, leaving a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 280 after subtracting 388 from 668.
Append the next digit (7) from the dividend to 280 and continue with: 2807 / 388

Step 4:
The number 388 fits into 2807 7 times, leaving a remainder of 91.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 2716 from 2807 and we're left with 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 388

Let's proceed to step 5:
The number 388 fits into 914 2 times, leaving a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtracting 776 from 914 leaves us with 138.
Take the next digit (1) from the dividend and append it to 138, then repeat: 1381 / 388

On to step 6:
The number 388 fits into 1381 3 times, leaving a remainder of 217.
Write down 3 as next digit of the result. 
Result so far: 1723.0
If we subtract 1164 from 1381, we get 217.
Take the next digit (8) from the dividend and append it to 217, then repeat: 2178 / 388

Advancing to step 7:
388 can be fit into 2178 5 times, resulting in a remainder of 238.
The next digit of our result is 5. 
Result so far: 17235.0
The remainder is 238 after subtracting 1940 from 2178.
Bring next digit (0) of the dividend behind the 238 and repeat the process: 2380 / 388

Step 8:
388 goes into 2380 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 172356.0
If we take 2328 away from 2380, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
520 divided by 388 is 1 with a remainder of 132.
The next digit of our result is 1. 
Result so far: 172356.1
Deduct 388 from 520 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
388 can be fit into 1320 3 times, resulting in a remainder of 156.
The next digit of our result is 3. 
Result so far: 172356.13
If we take 1164 away from 1320, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 11:
388 goes into 1560 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 172356.134
The remainder is 8 after subtracting 1552 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
388 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 172356.134
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 388, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 172356.13402
If we take 776 away from 800, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
The number 388 fits into 240 0 times, leaving a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 172356.13402
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
2400 divided by 388 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 172356.1340206
Subtracting 2328 from 2400 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
If we divide 720 by 388, we get 1 and a remainder of 332.
The next digit of our result is 1. 
Result so far: 172356.13402061
Subtracting 388 from 720 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

In conclusion, the division gives 172356.13402061 with a balance of 3.32e-07.
