86781321 divided by 430 
We're looking to find how many times 430 goes into 86781321.

On to step 1:
The number 430 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 430

Going ahead to step 2:
430 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 430

Moving on to step 3:
The number 430 fits into 867 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 7 after subtracting 860 from 867.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 430

Advancing to step 4:
78 divided by 430 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 78, we end up with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 430

On to step 5:
781 divided by 430 is 1 with a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
If we subtract 430 from 781, we get 351.
Fetch the next digit (3) from the dividend, attach it to 351 and continue: 3513 / 430

Going ahead to step 6:
430 can be fit into 3513 8 times, resulting in a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 2018.0
Deduct 3440 from 3513 and we're left with 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 430

Moving on to step 7:
430 goes into 732 1 times with a remainder of 302.
The next digit of our result is 1. 
Result so far: 20181.0
Subtracting 430 from 732 leaves us with 302.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 430

On to step 8:
430 can be fit into 3021 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 201817.0
Subtract 3010 from 3021 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 430 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 201817.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
1100 divided by 430 is 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 201817.02
Subtract 860 from 1100 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
When dividing 2400 by 430, we get 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 201817.025
Subtracting 2150 from 2400 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
When dividing 2500 by 430, we get 5 with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 201817.0255
If we subtract 2150 from 2500, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 201817.0255 and a remainder of 0.0035.
