84505410 divided by 678 
Our goal is to divide 84505410 by 678.

Going ahead to step 1:
If we divide 8 by 678, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 678

Moving on to step 2:
If we divide 84 by 678, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 678

Advancing to step 3:
678 can be fit into 845 1 times, resulting in a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 678 from 845 to get 167.
Grab the next digit (0) from the dividend, add it to 167, then carry on: 1670 / 678

Moving on to step 4:
When dividing 1670 by 678, we get 2 with a remainder of 314.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1356 from 1670 to get 314.
Grab the next digit (5) from the dividend, add it to 314, then carry on: 3145 / 678

Let's proceed to step 5:
678 can be fit into 3145 4 times, resulting in a remainder of 433.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtracting 2712 from 3145 leaves us with 433.
Fetch the next digit (4) from the dividend, attach it to 433 and continue: 4334 / 678

Let's proceed to step 6:
The number 678 fits into 4334 6 times, leaving a remainder of 266.
Record the quotient 6 as the next digit in the result. 
Result so far: 1246.0
If we subtract 4068 from 4334, we get 266.
Grab the next digit (1) from the dividend, add it to 266, then carry on: 2661 / 678

On to step 7:
2661 divided by 678 is 3 with a remainder of 627.
Put 3 as the next digit of the answer. 
Result so far: 12463.0
If we take 2034 away from 2661, we end up with 627.
Fetch the next digit (0) from the dividend, attach it to 627 and continue: 6270 / 678

Let's proceed to step 8:
6270 divided by 678 is 9 with a remainder of 168.
Record the quotient 9 as the next digit in the result. 
Result so far: 124639.0
Subtracting 6102 from 6270 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 9:
678 goes into 1680 2 times with a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 124639.2
If we take 1356 away from 1680, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
3240 divided by 678 is 4 with a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 124639.24
Subtracting 2712 from 3240 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 11:
If we divide 5280 by 678, we get 7 and a remainder of 534.
Use 7 as the next digit of our solution. 
Result so far: 124639.247
If we subtract 4746 from 5280, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 12:
When dividing 5340 by 678, we get 7 with a remainder of 594.
Use 7 as the next digit of our solution. 
Result so far: 124639.2477
Deduct 4746 from 5340 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Our division results in 124639.2477 with a remaining 0.00594.
