We look at the division of 81643206 by 378 
We're looking to find how many times 378 goes into 81643206.

Moving on to step 1:
If we divide 8 by 378, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 378

Let's proceed to step 2:
When dividing 81 by 378, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 378

Going ahead to step 3:
If we divide 816 by 378, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 60 after subtracting 756 from 816.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 378

Moving on to step 4:
378 can be fit into 604 1 times, resulting in a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 378 from 604 leaves us with 226.
Take the next digit (3) from the dividend and append it to 226, then repeat: 2263 / 378

Moving on to step 5:
378 goes into 2263 5 times with a remainder of 373.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Deduct 1890 from 2263 and we're left with 373.
Grab the next digit (2) from the dividend, add it to 373, then carry on: 3732 / 378

Moving on to step 6:
If we divide 3732 by 378, we get 9 and a remainder of 330.
The number 9 becomes the next digit in our result. 
Result so far: 2159.0
If we subtract 3402 from 3732, we get 330.
Take the next digit (0) from the dividend and append it to 330, then repeat: 3300 / 378

Moving on to step 7:
3300 divided by 378 is 8 with a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 21598.0
Subtract 3024 from 3300 to get 276.
Take the next digit (6) from the dividend and append it to 276, then repeat: 2766 / 378

Going ahead to step 8:
378 can be fit into 2766 7 times, resulting in a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 215987.0
The remainder is 120 after subtracting 2646 from 2766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
378 goes into 1200 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 215987.3
Subtracting 1134 from 1200 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
When dividing 660 by 378, we get 1 with a remainder of 282.
The number 1 becomes the next digit in our result. 
Result so far: 215987.31
If we subtract 378 from 660, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 11:
378 goes into 2820 7 times with a remainder of 174.
Record the quotient 7 as the next digit in the result. 
Result so far: 215987.317
Subtract 2646 from 2820 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 12:
378 can be fit into 1740 4 times, resulting in a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 215987.3174
If we take 1512 away from 1740, we end up 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.

Moving on to step 13:
378 goes into 2280 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 215987.31746
Subtracting 2268 from 2280 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
The number 378 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 215987.31746
If we subtract 0 from 120, we 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.

Let's proceed to step 15:
378 can be fit into 1200 3 times, resulting in a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 215987.3174603
Subtracting 1134 from 1200 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
660 divided by 378 is 1 with a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 215987.31746031
The remainder is 282 after subtracting 378 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Our division results in 215987.31746031 with a remaining 2.82e-07.
