We're dividing 85559866 by 378 
Our goal is to divide 85559866 by 378.

Advancing to step 1:
8 divided by 378 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 378

Moving on to step 2:
The number 378 fits into 85 0 times, leaving a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 378

Step 3:
855 divided by 378 is 2 with a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 99 after subtracting 756 from 855.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 378

On to step 4:
If we divide 995 by 378, we get 2 and a remainder of 239.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 756 from 995, we get 239.
Take the next digit (9) from the dividend and append it to 239, then repeat: 2399 / 378

Moving on to step 5:
The number 378 fits into 2399 6 times, leaving a remainder of 131.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Deduct 2268 from 2399 and we're left with 131.
Append the next digit (8) from the dividend to 131 and continue with: 1318 / 378

Step 6:
If we divide 1318 by 378, we get 3 and a remainder of 184.
Put 3 as the next digit of the answer. 
Result so far: 2263.0
The remainder is 184 after subtracting 1134 from 1318.
Append the next digit (6) from the dividend to 184 and continue with: 1846 / 378

Step 7:
1846 divided by 378 is 4 with a remainder of 334.
Use 4 as the next digit of our solution. 
Result so far: 22634.0
If we subtract 1512 from 1846, we get 334.
Take the next digit (6) from the dividend and append it to 334, then repeat: 3346 / 378

Going ahead to step 8:
The number 378 fits into 3346 8 times, leaving a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 226348.0
Subtract 3024 from 3346 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 9:
3220 divided by 378 is 8 with a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 226348.8
Subtracting 3024 from 3220 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 10:
378 can be fit into 1960 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 226348.85
If we subtract 1890 from 1960, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
378 goes into 700 1 times with a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 226348.851
The remainder is 322 after subtracting 378 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 12:
The number 378 fits into 3220 8 times, leaving a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 226348.8518
Subtracting 3024 from 3220 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 13:
The number 378 fits into 1960 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 226348.85185
If we subtract 1890 from 1960, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
When dividing 700 by 378, we get 1 with a remainder of 322.
The next digit of our result is 1. 
Result so far: 226348.851851
Subtract 378 from 700 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 15:
If we divide 3220 by 378, we get 8 and a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 226348.8518518
If we subtract 3024 from 3220, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 16:
If we divide 1960 by 378, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 226348.85185185
Subtract 1890 from 1960 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 226348.85185185, and the remainder is 7e-08.
