77430130 ÷ 861 
We want to divide 77430130 by 861.

Let's proceed to step 1:
861 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 861

Let's proceed to step 2:
861 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 861

On to step 3:
When dividing 774 by 861, we get 0 with a remainder of 774.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 774 and we're left with 774.
Grab the next digit (3) from the dividend, add it to 774, then carry on: 7743 / 861

Let's proceed to step 4:
861 can be fit into 7743 8 times, resulting in a remainder of 855.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 855 after subtracting 6888 from 7743.
Bring next digit (0) of the dividend behind the 855 and repeat the process: 8550 / 861

Step 5:
861 goes into 8550 9 times with a remainder of 801.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 7749 from 8550 leaves us with 801.
Fetch the next digit (1) from the dividend, attach it to 801 and continue: 8011 / 861

Step 6:
8011 divided by 861 is 9 with a remainder of 262.
Write down 9 as next digit of the result. 
Result so far: 899.0
Subtracting 7749 from 8011 leaves us with 262.
Fetch the next digit (3) from the dividend, attach it to 262 and continue: 2623 / 861

On to step 7:
When dividing 2623 by 861, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 8993.0
The remainder is 40 after subtracting 2583 from 2623.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 861

Step 8:
When dividing 400 by 861, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 89930.0
Deduct 0 from 400 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.

Going ahead to step 9:
861 can be fit into 4000 4 times, resulting in a remainder of 556.
Use 4 as the next digit of our solution. 
Result so far: 89930.4
The remainder is 556 after subtracting 3444 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 10:
If we divide 5560 by 861, we get 6 and a remainder of 394.
Write down 6 as next digit of the result. 
Result so far: 89930.46
Subtracting 5166 from 5560 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 11:
The number 861 fits into 3940 4 times, leaving a remainder of 496.
Write down 4 as next digit of the result. 
Result so far: 89930.464
If we subtract 3444 from 3940, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 12:
If we divide 4960 by 861, we get 5 and a remainder of 655.
Put 5 as the next digit of the answer. 
Result so far: 89930.4645
If we take 4305 away from 4960, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Let's proceed to step 13:
When dividing 6550 by 861, we get 7 with a remainder of 523.
Use 7 as the next digit of our solution. 
Result so far: 89930.46457
Subtracting 6027 from 6550 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 14:
861 can be fit into 5230 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 89930.464576
If we take 5166 away from 5230, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
If we divide 640 by 861, we get 0 and a remainder of 640.
The next digit of our result is 0. 
Result so far: 89930.464576
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 16:
If we divide 6400 by 861, we get 7 and a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 89930.46457607
If we take 6027 away from 6400, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Our division results in 89930.46457607 with a remaining 3.73e-07.
