11397560 ÷ 678 
Our goal is to divide 11397560 by 678.

Going ahead to step 1:
When dividing 1 by 678, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 678

Let's proceed to step 2:
The number 678 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 678

Let's proceed to step 3:
678 goes into 113 0 times with a remainder of 113.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 113 to get 113.
Include the next digit (9) from the dividend after 113, then repeat: 1139 / 678

Advancing to step 4:
If we divide 1139 by 678, we get 1 and a remainder of 461.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 678 from 1139 and we're left with 461.
Grab the next digit (7) from the dividend, add it to 461, then carry on: 4617 / 678

Going ahead to step 5:
678 can be fit into 4617 6 times, resulting in a remainder of 549.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 4068 away from 4617, we end up with 549.
Append the next digit (5) from the dividend to 549 and continue with: 5495 / 678

On to step 6:
The number 678 fits into 5495 8 times, leaving a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Deduct 5424 from 5495 and we're left with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 678

Advancing to step 7:
678 can be fit into 716 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1681.0
The remainder is 38 after subtracting 678 from 716.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 678

On to step 8:
380 divided by 678 is 0 with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 16810.0
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 9:
678 can be fit into 3800 5 times, resulting in a remainder of 410.
The next digit of our result is 5. 
Result so far: 16810.5
Subtracting 3390 from 3800 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
678 can be fit into 4100 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 16810.56
Deduct 4068 from 4100 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
678 can be fit into 320 0 times, resulting in a remainder of 320.
The next digit of our result is 0. 
Result so far: 16810.56
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
If we divide 3200 by 678, we get 4 and a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 16810.5604
If we subtract 2712 from 3200, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 13:
678 goes into 4880 7 times with a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 16810.56047
Deduct 4746 from 4880 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 14:
If we divide 1340 by 678, we get 1 and a remainder of 662.
Put 1 as the next digit of the answer. 
Result so far: 16810.560471
Subtract 678 from 1340 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Moving on to step 15:
The number 678 fits into 6620 9 times, leaving a remainder of 518.
The next digit of our result is 9. 
Result so far: 16810.5604719
Subtract 6102 from 6620 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Advancing to step 16:
If we divide 5180 by 678, we get 7 and a remainder of 434.
The next digit of our result is 7. 
Result so far: 16810.56047197
If we subtract 4746 from 5180, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

The quotient of the division is 16810.56047197, and the remainder is 4.34e-07.
