78494046 ÷ 906 
Our goal is to divide 78494046 by 906.

Moving on to step 1:
906 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 906

Let's proceed to step 2:
When dividing 78 by 906, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 906

On to step 3:
784 divided by 906 is 0 with a remainder of 784.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 784, we end up with 784.
Grab the next digit (9) from the dividend, add it to 784, then carry on: 7849 / 906

Going ahead to step 4:
7849 divided by 906 is 8 with a remainder of 601.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7248 away from 7849, we end up with 601.
Fetch the next digit (4) from the dividend, attach it to 601 and continue: 6014 / 906

Moving on to step 5:
When dividing 6014 by 906, we get 6 with a remainder of 578.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 5436 from 6014, we get 578.
Include the next digit (0) from the dividend after 578, then repeat: 5780 / 906

Advancing to step 6:
If we divide 5780 by 906, we get 6 and a remainder of 344.
The next digit of our result is 6. 
Result so far: 866.0
Subtract 5436 from 5780 to get 344.
Grab the next digit (4) from the dividend, add it to 344, then carry on: 3444 / 906

Going ahead to step 7:
When dividing 3444 by 906, we get 3 with a remainder of 726.
The number 3 becomes the next digit in our result. 
Result so far: 8663.0
Deduct 2718 from 3444 and we're left with 726.
Take the next digit (6) from the dividend and append it to 726, then repeat: 7266 / 906

Step 8:
906 goes into 7266 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 86638.0
Subtract 7248 from 7266 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
If we divide 180 by 906, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 86638.0
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
906 goes into 1800 1 times with a remainder of 894.
Write down 1 as next digit of the result. 
Result so far: 86638.01
Deduct 906 from 1800 and we're left with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Advancing to step 11:
When dividing 8940 by 906, we get 9 with a remainder of 786.
The number 9 becomes the next digit in our result. 
Result so far: 86638.019
The remainder is 786 after subtracting 8154 from 8940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Let's proceed to step 12:
If we divide 7860 by 906, we get 8 and a remainder of 612.
The number 8 becomes the next digit in our result. 
Result so far: 86638.0198
Subtracting 7248 from 7860 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 13:
906 goes into 6120 6 times with a remainder of 684.
Write down 6 as next digit of the result. 
Result so far: 86638.01986
If we subtract 5436 from 6120, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 14:
6840 divided by 906 is 7 with a remainder of 498.
Use 7 as the next digit of our solution. 
Result so far: 86638.019867
The remainder is 498 after subtracting 6342 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 15:
When dividing 4980 by 906, we get 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 86638.0198675
The remainder is 450 after subtracting 4530 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 16:
If we divide 4500 by 906, we get 4 and a remainder of 876.
The number 4 becomes the next digit in our result. 
Result so far: 86638.01986754
Subtract 3624 from 4500 to get 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

After the division, we end up with 86638.01986754 and a remainder of 8.76e-07.
