98406915 ÷ 378 
We want to divide 98406915 by 378.

On to step 1:
378 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 378

Moving on to step 2:
378 goes into 98 0 times with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 378

Moving on to step 3:
378 can be fit into 984 2 times, resulting in a remainder of 228.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 756 from 984 and we're left with 228.
Grab the next digit (0) from the dividend, add it to 228, then carry on: 2280 / 378

Let's proceed to step 4:
2280 divided by 378 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 2268 from 2280 to get 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 378

Step 5:
If we divide 126 by 378, we get 0 and a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 260.0
Deduct 0 from 126 and we're left with 126.
Include the next digit (9) from the dividend after 126, then repeat: 1269 / 378

Advancing to step 6:
378 can be fit into 1269 3 times, resulting in a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 2603.0
Subtract 1134 from 1269 to get 135.
Append the next digit (1) from the dividend to 135 and continue with: 1351 / 378

On to step 7:
1351 divided by 378 is 3 with a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 26033.0
If we take 1134 away from 1351, we end up with 217.
Bring next digit (5) of the dividend behind the 217 and repeat the process: 2175 / 378

Let's proceed to step 8:
2175 divided by 378 is 5 with a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 260335.0
Subtract 1890 from 2175 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 9:
2850 divided by 378 is 7 with a remainder of 204.
Write down 7 as next digit of the result. 
Result so far: 260335.7
If we take 2646 away from 2850, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 10:
If we divide 2040 by 378, we get 5 and a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 260335.75
Subtract 1890 from 2040 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
378 goes into 1500 3 times with a remainder of 366.
Record the quotient 3 as the next digit in the result. 
Result so far: 260335.753
Subtracting 1134 from 1500 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 12:
When dividing 3660 by 378, we get 9 with a remainder of 258.
The next digit of our result is 9. 
Result so far: 260335.7539
Subtracting 3402 from 3660 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 13:
If we divide 2580 by 378, we get 6 and a remainder of 312.
Put 6 as the next digit of the answer. 
Result so far: 260335.75396
If we subtract 2268 from 2580, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 14:
378 can be fit into 3120 8 times, resulting in a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 260335.753968
Subtracting 3024 from 3120 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
960 divided by 378 is 2 with a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 260335.7539682
Subtract 756 from 960 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 16:
The number 378 fits into 2040 5 times, leaving a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 260335.75396825
If we subtract 1890 from 2040, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 260335.75396825 with a remaining 1.5e-07.
