56122761 ÷ 390 
Our goal is to divide 56122761 by 390.

On to step 1:
The number 390 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 390

On to step 2:
390 goes into 56 0 times with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 390

Step 3:
If we divide 561 by 390, we get 1 and a remainder of 171.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 171 after subtracting 390 from 561.
Grab the next digit (2) from the dividend, add it to 171, then carry on: 1712 / 390

Going ahead to step 4:
If we divide 1712 by 390, we get 4 and a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 152 after subtracting 1560 from 1712.
Fetch the next digit (2) from the dividend, attach it to 152 and continue: 1522 / 390

On to step 5:
390 can be fit into 1522 3 times, resulting in a remainder of 352.
The next digit of our result is 3. 
Result so far: 143.0
The remainder is 352 after subtracting 1170 from 1522.
Append the next digit (7) from the dividend to 352 and continue with: 3527 / 390

Let's proceed to step 6:
390 goes into 3527 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1439.0
Deduct 3510 from 3527 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 390

On to step 7:
390 can be fit into 176 0 times, resulting in a remainder of 176.
The next digit of our result is 0. 
Result so far: 14390.0
If we take 0 away from 176, we end up with 176.
Bring next digit (1) of the dividend behind the 176 and repeat the process: 1761 / 390

Moving on to step 8:
1761 divided by 390 is 4 with a remainder of 201.
The number 4 becomes the next digit in our result. 
Result so far: 143904.0
Subtracting 1560 from 1761 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 9:
390 can be fit into 2010 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 143904.5
The remainder is 60 after subtracting 1950 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 390, we get 1 with a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 143904.51
Subtract 390 from 600 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 11:
When dividing 2100 by 390, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 143904.515
Subtract 1950 from 2100 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
390 goes into 1500 3 times with a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 143904.5153
Deduct 1170 from 1500 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 13:
3300 divided by 390 is 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 143904.51538
If we subtract 3120 from 3300, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
390 goes into 1800 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 143904.515384
If we take 1560 away from 1800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
When dividing 2400 by 390, we get 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 143904.5153846
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
390 goes into 600 1 times with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 143904.51538461
If we take 390 away from 600, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 143904.51538461 with a remaining 2.1e-07.
