26669954 ÷ 78 
Our goal is to divide 26669954 by 78.

Advancing to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 78

Step 2:
When dividing 26 by 78, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 78

Moving on to step 3:
The number 78 fits into 266 3 times, leaving a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 234 from 266 leaves us with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 78

Step 4:
The number 78 fits into 326 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtracting 312 from 326 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 78

Step 5:
If we divide 149 by 78, we get 1 and a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 341.0
Subtracting 78 from 149 leaves us with 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 78

Step 6:
719 divided by 78 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 3419.0
Deduct 702 from 719 and we're left with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 78

Advancing to step 7:
175 divided by 78 is 2 with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 34192.0
Subtract 156 from 175 to get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 78

Moving on to step 8:
When dividing 194 by 78, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 341922.0
Deduct 156 from 194 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.

Step 9:
If we divide 380 by 78, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 341922.4
Subtracting 312 from 380 leaves us with 68.
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:
680 divided by 78 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 341922.48
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
When dividing 560 by 78, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 341922.487
Deduct 546 from 560 and we're left with 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.
Put 1 as the next digit of the answer. 
Result so far: 341922.4871
Subtracting 78 from 140 leaves us 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.

Let's proceed to step 13:
620 divided by 78 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 341922.48717
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.

Moving on to step 14:
740 divided by 78 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 341922.487179
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 15:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 341922.4871794
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.

On to step 16:
680 divided by 78 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 341922.48717948
Deduct 624 from 680 and we're left 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.

The final outcome is 341922.48717948, with a leftover of 5.6e-08.
