We divide 78980934 by 907
We want to figure out the number of times 78980934 can be divided by 907.

On to step 1:
The number 907 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 907

Moving on to step 2:
When dividing 78 by 907, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 907

Step 3:
907 can be fit into 789 0 times, resulting in a remainder of 789.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 789, we get 789.
Include the next digit (8) from the dividend after 789, then repeat: 7898 / 907

Moving on to step 4:
If we divide 7898 by 907, we get 8 and a remainder of 642.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7256 from 7898 leaves us with 642.
Append the next digit (0) from the dividend to 642 and continue with: 6420 / 907

Step 5:
6420 divided by 907 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 6349 from 6420 and we're left with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 907

Moving on to step 6:
When dividing 719 by 907, we get 0 with a remainder of 719.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
If we subtract 0 from 719, we get 719.
Append the next digit (3) from the dividend to 719 and continue with: 7193 / 907

Let's proceed to step 7:
When dividing 7193 by 907, we get 7 with a remainder of 844.
Write down 7 as next digit of the result. 
Result so far: 8707.0
Deduct 6349 from 7193 and we're left with 844.
Take the next digit (4) from the dividend and append it to 844, then repeat: 8444 / 907

Advancing to step 8:
If we divide 8444 by 907, we get 9 and a remainder of 281.
The number 9 becomes the next digit in our result. 
Result so far: 87079.0
Subtract 8163 from 8444 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 9:
The number 907 fits into 2810 3 times, leaving a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 87079.3
The remainder is 89 after subtracting 2721 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 10:
The number 907 fits into 890 0 times, leaving a remainder of 890.
The next digit of our result is 0. 
Result so far: 87079.3
Deduct 0 from 890 and we're left with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Let's proceed to step 11:
When dividing 8900 by 907, we get 9 with a remainder of 737.
Record the quotient 9 as the next digit in the result. 
Result so far: 87079.309
The remainder is 737 after subtracting 8163 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Advancing to step 12:
7370 divided by 907 is 8 with a remainder of 114.
The next digit of our result is 8. 
Result so far: 87079.3098
The remainder is 114 after subtracting 7256 from 7370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 13:
907 goes into 1140 1 times with a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 87079.30981
The remainder is 233 after subtracting 907 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 14:
If we divide 2330 by 907, we get 2 and a remainder of 516.
The number 2 becomes the next digit in our result. 
Result so far: 87079.309812
Subtract 1814 from 2330 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 15:
If we divide 5160 by 907, we get 5 and a remainder of 625.
The number 5 becomes the next digit in our result. 
Result so far: 87079.3098125
If we subtract 4535 from 5160, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Step 16:
If we divide 6250 by 907, we get 6 and a remainder of 808.
Record the quotient 6 as the next digit in the result. 
Result so far: 87079.30981256
Subtract 5442 from 6250 to get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

The final result is 87079.30981256 with a remainder of 8.08e-07.
