We divide 78930278 by 423
We want to divide 78930278 by 423.

Going ahead to step 1:
If we divide 7 by 423, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 423

Step 2:
When dividing 78 by 423, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 423

Advancing to step 3:
When dividing 789 by 423, we get 1 with a remainder of 366.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 366 after subtracting 423 from 789.
Fetch the next digit (3) from the dividend, attach it to 366 and continue: 3663 / 423

Advancing to step 4:
When dividing 3663 by 423, we get 8 with a remainder of 279.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 279 after subtracting 3384 from 3663.
Fetch the next digit (0) from the dividend, attach it to 279 and continue: 2790 / 423

Advancing to step 5:
If we divide 2790 by 423, we get 6 and a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 186.0
Deduct 2538 from 2790 and we're left with 252.
Grab the next digit (2) from the dividend, add it to 252, then carry on: 2522 / 423

Step 6:
423 can be fit into 2522 5 times, resulting in a remainder of 407.
Use 5 as the next digit of our solution. 
Result so far: 1865.0
Subtract 2115 from 2522 to get 407.
Take the next digit (7) from the dividend and append it to 407, then repeat: 4077 / 423

Step 7:
If we divide 4077 by 423, we get 9 and a remainder of 270.
Put 9 as the next digit of the answer. 
Result so far: 18659.0
Subtracting 3807 from 4077 leaves us with 270.
Grab the next digit (8) from the dividend, add it to 270, then carry on: 2708 / 423

Going ahead to step 8:
423 can be fit into 2708 6 times, resulting in a remainder of 170.
The number 6 becomes the next digit in our result. 
Result so far: 186596.0
Deduct 2538 from 2708 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
423 can be fit into 1700 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 186596.4
If we take 1692 away from 1700, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 423 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 186596.4
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
If we divide 800 by 423, we get 1 and a remainder of 377.
Use 1 as the next digit of our solution. 
Result so far: 186596.401
Deduct 423 from 800 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 12:
3770 divided by 423 is 8 with a remainder of 386.
Write down 8 as next digit of the result. 
Result so far: 186596.4018
Deduct 3384 from 3770 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 13:
423 goes into 3860 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 186596.40189
The remainder is 53 after subtracting 3807 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
The number 423 fits into 530 1 times, leaving a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 186596.401891
Subtract 423 from 530 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 15:
423 goes into 1070 2 times with a remainder of 224.
The next digit of our result is 2. 
Result so far: 186596.4018912
Deduct 846 from 1070 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 16:
2240 divided by 423 is 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 186596.40189125
The remainder is 125 after subtracting 2115 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 186596.40189125 with a remaining 1.25e-07.
