Let's divide 85997139 by 612
Our goal is to divide 85997139 by 612.

Going ahead to step 1:
If we divide 8 by 612, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 612

Step 2:
If we divide 85 by 612, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 612

On to step 3:
When dividing 859 by 612, we get 1 with a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 612 from 859 to get 247.
Take the next digit (9) from the dividend and append it to 247, then repeat: 2479 / 612

Step 4:
If we divide 2479 by 612, we get 4 and a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 2448 from 2479 leaves us with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 612

Let's proceed to step 5:
612 goes into 317 0 times with a remainder of 317.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
The remainder is 317 after subtracting 0 from 317.
Take the next digit (1) from the dividend and append it to 317, then repeat: 3171 / 612

On to step 6:
When dividing 3171 by 612, we get 5 with a remainder of 111.
Write down 5 as next digit of the result. 
Result so far: 1405.0
Subtracting 3060 from 3171 leaves us with 111.
Append the next digit (3) from the dividend to 111 and continue with: 1113 / 612

Advancing to step 7:
When dividing 1113 by 612, we get 1 with a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 14051.0
Subtracting 612 from 1113 leaves us with 501.
Grab the next digit (9) from the dividend, add it to 501, then carry on: 5019 / 612

On to step 8:
The number 612 fits into 5019 8 times, leaving a remainder of 123.
Put 8 as the next digit of the answer. 
Result so far: 140518.0
Subtracting 4896 from 5019 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
When dividing 1230 by 612, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 140518.2
If we take 1224 away from 1230, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
612 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 140518.2
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
612 goes into 600 0 times with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 140518.2
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 140518.2 with a balance of 0.06.
