61308593 divided by 399 
Our goal is to divide 61308593 by 399.

On to step 1:
If we divide 6 by 399, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 399

Moving on to step 2:
399 can be fit into 61 0 times, resulting in a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 399

Let's proceed to step 3:
If we divide 613 by 399, we get 1 and a remainder of 214.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 399 from 613 to get 214.
Include the next digit (0) from the dividend after 214, then repeat: 2140 / 399

Going ahead to step 4:
399 goes into 2140 5 times with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 1995 from 2140 and we're left with 145.
Grab the next digit (8) from the dividend, add it to 145, then carry on: 1458 / 399

Let's proceed to step 5:
1458 divided by 399 is 3 with a remainder of 261.
Put 3 as the next digit of the answer. 
Result so far: 153.0
The remainder is 261 after subtracting 1197 from 1458.
Fetch the next digit (5) from the dividend, attach it to 261 and continue: 2615 / 399

On to step 6:
When dividing 2615 by 399, we get 6 with a remainder of 221.
The number 6 becomes the next digit in our result. 
Result so far: 1536.0
Subtracting 2394 from 2615 leaves us with 221.
Bring next digit (9) of the dividend behind the 221 and repeat the process: 2219 / 399

Let's proceed to step 7:
The number 399 fits into 2219 5 times, leaving a remainder of 224.
Record the quotient 5 as the next digit in the result. 
Result so far: 15365.0
Subtract 1995 from 2219 to get 224.
Grab the next digit (3) from the dividend, add it to 224, then carry on: 2243 / 399

Advancing to step 8:
399 goes into 2243 5 times with a remainder of 248.
The next digit of our result is 5. 
Result so far: 153655.0
Subtracting 1995 from 2243 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 9:
The number 399 fits into 2480 6 times, leaving a remainder of 86.
The next digit of our result is 6. 
Result so far: 153655.6
Deduct 2394 from 2480 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 10:
399 can be fit into 860 2 times, resulting in a remainder of 62.
The next digit of our result is 2. 
Result so far: 153655.62
Subtracting 798 from 860 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
399 goes into 620 1 times with a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 153655.621
Subtract 399 from 620 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 12:
399 can be fit into 2210 5 times, resulting in a remainder of 215.
The next digit of our result is 5. 
Result so far: 153655.6215
The remainder is 215 after subtracting 1995 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 13:
When dividing 2150 by 399, we get 5 with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 153655.62155
Subtract 1995 from 2150 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 153655.62155, with a leftover of 0.000155.
