84515089 divided by 378 
We want to divide 84515089 by 378.

Step 1:
When dividing 8 by 378, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 378

Step 2:
378 can be fit into 84 0 times, resulting in a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 378

On to step 3:
378 goes into 845 2 times with a remainder of 89.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 756 from 845, we get 89.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 378

Moving on to step 4:
If we divide 891 by 378, we get 2 and a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 135 after subtracting 756 from 891.
Append the next digit (5) from the dividend to 135 and continue with: 1355 / 378

Advancing to step 5:
378 can be fit into 1355 3 times, resulting in a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
Subtracting 1134 from 1355 leaves us with 221.
Grab the next digit (0) from the dividend, add it to 221, then carry on: 2210 / 378

Advancing to step 6:
378 can be fit into 2210 5 times, resulting in a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 2235.0
If we take 1890 away from 2210, we end up with 320.
Include the next digit (8) from the dividend after 320, then repeat: 3208 / 378

On to step 7:
If we divide 3208 by 378, we get 8 and a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 22358.0
Subtracting 3024 from 3208 leaves us with 184.
Grab the next digit (9) from the dividend, add it to 184, then carry on: 1849 / 378

Advancing to step 8:
1849 divided by 378 is 4 with a remainder of 337.
Record the quotient 4 as the next digit in the result. 
Result so far: 223584.0
The remainder is 337 after subtracting 1512 from 1849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 9:
3370 divided by 378 is 8 with a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 223584.8
If we subtract 3024 from 3370, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 10:
If we divide 3460 by 378, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 223584.89
If we take 3402 away from 3460, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
The number 378 fits into 580 1 times, leaving a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 223584.891
The remainder is 202 after subtracting 378 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 12:
If we divide 2020 by 378, we get 5 and a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 223584.8915
Deduct 1890 from 2020 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
If we divide 1300 by 378, we get 3 and a remainder of 166.
Record the quotient 3 as the next digit in the result. 
Result so far: 223584.89153
Deduct 1134 from 1300 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 14:
When dividing 1660 by 378, we get 4 with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 223584.891534
Subtract 1512 from 1660 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
378 can be fit into 1480 3 times, resulting in a remainder of 346.
The number 3 becomes the next digit in our result. 
Result so far: 223584.8915343
Deduct 1134 from 1480 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 16:
3460 divided by 378 is 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 223584.89153439
If we subtract 3402 from 3460, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 223584.89153439 with a balance of 5.8e-08.
