84139674 divided by 784 
Our goal is to divide 84139674 by 784.

Advancing to step 1:
8 divided by 784 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 784

Moving on to step 2:
If we divide 84 by 784, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 784

Advancing to step 3:
The number 784 fits into 841 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 784 from 841 leaves us with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 784

Advancing to step 4:
784 goes into 573 0 times with a remainder of 573.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 573, we get 573.
Grab the next digit (9) from the dividend, add it to 573, then carry on: 5739 / 784

On to step 5:
When dividing 5739 by 784, we get 7 with a remainder of 251.
The next digit of our result is 7. 
Result so far: 107.0
If we take 5488 away from 5739, we end up with 251.
Fetch the next digit (6) from the dividend, attach it to 251 and continue: 2516 / 784

Going ahead to step 6:
When dividing 2516 by 784, we get 3 with a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 1073.0
Subtracting 2352 from 2516 leaves us with 164.
Grab the next digit (7) from the dividend, add it to 164, then carry on: 1647 / 784

Advancing to step 7:
1647 divided by 784 is 2 with a remainder of 79.
Put 2 as the next digit of the answer. 
Result so far: 10732.0
Deduct 1568 from 1647 and we're left with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 784

Let's proceed to step 8:
When dividing 794 by 784, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 107321.0
Subtracting 784 from 794 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 784, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 107321.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
784 can be fit into 1000 1 times, resulting in a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 107321.01
Deduct 784 from 1000 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
If we divide 2160 by 784, we get 2 and a remainder of 592.
Record the quotient 2 as the next digit in the result. 
Result so far: 107321.012
Subtract 1568 from 2160 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 12:
When dividing 5920 by 784, we get 7 with a remainder of 432.
The number 7 becomes the next digit in our result. 
Result so far: 107321.0127
Subtract 5488 from 5920 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 13:
The number 784 fits into 4320 5 times, leaving a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 107321.01275
Deduct 3920 from 4320 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 14:
The number 784 fits into 4000 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 107321.012755
If we take 3920 away from 4000, 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.

After the division, we end up with 107321.012755 and a remainder of 8e-06.
