168620 divided by 78 
We want to divide 168620 by 78.

Let's proceed to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 78

Moving on to step 2:
78 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 78

Advancing to step 3:
The number 78 fits into 168 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 156 from 168 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 78

Step 4:
78 goes into 126 1 times with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 78 away from 126, we end up with 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 78

Let's proceed to step 5:
482 divided by 78 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we subtract 468 from 482, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 78

Moving on to step 6:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 2161.0
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 2161.7
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 2161.79
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 2161.794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
When dividing 680 by 78, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 2161.7948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 2161.79487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
If we divide 140 by 78, we get 1 and a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 2161.794871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
620 divided by 78 is 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 2161.7948717
If we subtract 546 from 620, we 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.

Moving on to step 14:
When dividing 740 by 78, we get 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 2161.79487179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 2161.79487179, with a leftover of 3.8e-08.
