78629214 ÷ 781 
Our goal is to divide 78629214 by 781.

Moving on to step 1:
The number 781 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 781

Moving on to step 2:
If we divide 78 by 781, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 781

Going ahead to step 3:
786 divided by 781 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 781 from 786 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 781

Moving on to step 4:
If we divide 52 by 781, we get 0 and a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 781

Let's proceed to step 5:
781 goes into 529 0 times with a remainder of 529.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 529 and we're left with 529.
Fetch the next digit (2) from the dividend, attach it to 529 and continue: 5292 / 781

Advancing to step 6:
If we divide 5292 by 781, we get 6 and a remainder of 606.
Use 6 as the next digit of our solution. 
Result so far: 1006.0
If we take 4686 away from 5292, we end up with 606.
Append the next digit (1) from the dividend to 606 and continue with: 6061 / 781

Advancing to step 7:
When dividing 6061 by 781, we get 7 with a remainder of 594.
The next digit of our result is 7. 
Result so far: 10067.0
If we take 5467 away from 6061, we end up with 594.
Grab the next digit (4) from the dividend, add it to 594, then carry on: 5944 / 781

Let's proceed to step 8:
When dividing 5944 by 781, we get 7 with a remainder of 477.
Record the quotient 7 as the next digit in the result. 
Result so far: 100677.0
If we subtract 5467 from 5944, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 9:
When dividing 4770 by 781, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 100677.6
If we take 4686 away from 4770, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
If we divide 840 by 781, we get 1 and a remainder of 59.
The next digit of our result is 1. 
Result so far: 100677.61
Subtracting 781 from 840 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
When dividing 590 by 781, we get 0 with a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 100677.61
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
781 goes into 5900 7 times with a remainder of 433.
The number 7 becomes the next digit in our result. 
Result so far: 100677.6107
Subtract 5467 from 5900 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 13:
The number 781 fits into 4330 5 times, leaving a remainder of 425.
The next digit of our result is 5. 
Result so far: 100677.61075
Subtracting 3905 from 4330 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 14:
The number 781 fits into 4250 5 times, leaving a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 100677.610755
If we subtract 3905 from 4250, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final result is 100677.610755 with a remainder of 3.45e-05.
