78621324 divided by 125 
Our goal is to divide 78621324 by 125.

Moving on to step 1:
The number 125 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 125

On to step 2:
78 divided by 125 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 125

Advancing to step 3:
125 can be fit into 786 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 750 away from 786, we end up with 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 125

On to step 4:
When dividing 362 by 125, we get 2 with a remainder of 112.
The next digit of our result is 2. 
Result so far: 62.0
Subtract 250 from 362 to get 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 125

Going ahead to step 5:
The number 125 fits into 1121 8 times, leaving a remainder of 121.
The next digit of our result is 8. 
Result so far: 628.0
The remainder is 121 after subtracting 1000 from 1121.
Grab the next digit (3) from the dividend, add it to 121, then carry on: 1213 / 125

Advancing to step 6:
1213 divided by 125 is 9 with a remainder of 88.
The next digit of our result is 9. 
Result so far: 6289.0
Deduct 1125 from 1213 and we're left with 88.
Append the next digit (2) from the dividend to 88 and continue with: 882 / 125

Moving on to step 7:
125 goes into 882 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 62897.0
Subtract 875 from 882 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 125

Moving on to step 8:
125 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 628970.0
Subtract 0 from 74 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
When dividing 740 by 125, we get 5 with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 628970.5
Subtracting 625 from 740 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
When dividing 1150 by 125, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 628970.59
Deduct 1125 from 1150 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
125 can be fit into 250 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 628970.592
If we take 250 away from 250, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
125 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 628970.592
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
The number 125 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 628970.592
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 628970.592, with a leftover of 0.0.
