51580406 divided by 860 
Our goal is to divide 51580406 by 860.

Moving on to step 1:
860 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 860

Going ahead to step 2:
860 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 860

Step 3:
If we divide 515 by 860, we get 0 and a remainder of 515.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 515 leaves us with 515.
Grab the next digit (8) from the dividend, add it to 515, then carry on: 5158 / 860

Step 4:
The number 860 fits into 5158 5 times, leaving a remainder of 858.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 4300 from 5158 leaves us with 858.
Fetch the next digit (0) from the dividend, attach it to 858 and continue: 8580 / 860

Going ahead to step 5:
860 goes into 8580 9 times with a remainder of 840.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 7740 from 8580, we get 840.
Include the next digit (4) from the dividend after 840, then repeat: 8404 / 860

Moving on to step 6:
The number 860 fits into 8404 9 times, leaving a remainder of 664.
Put 9 as the next digit of the answer. 
Result so far: 599.0
If we take 7740 away from 8404, we end up with 664.
Bring next digit (0) of the dividend behind the 664 and repeat the process: 6640 / 860

On to step 7:
6640 divided by 860 is 7 with a remainder of 620.
Write down 7 as next digit of the result. 
Result so far: 5997.0
Subtract 6020 from 6640 to get 620.
Include the next digit (6) from the dividend after 620, then repeat: 6206 / 860

Going ahead to step 8:
If we divide 6206 by 860, we get 7 and a remainder of 186.
Use 7 as the next digit of our solution. 
Result so far: 59977.0
Deduct 6020 from 6206 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 9:
1860 divided by 860 is 2 with a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 59977.2
Subtract 1720 from 1860 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
When dividing 1400 by 860, we get 1 with a remainder of 540.
Record the quotient 1 as the next digit in the result. 
Result so far: 59977.21
If we subtract 860 from 1400, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
If we divide 5400 by 860, we get 6 and a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 59977.216
Subtract 5160 from 5400 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.

Step 12:
When dividing 2400 by 860, we get 2 with a remainder of 680.
Record the quotient 2 as the next digit in the result. 
Result so far: 59977.2162
If we subtract 1720 from 2400, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
6800 divided by 860 is 7 with a remainder of 780.
The next digit of our result is 7. 
Result so far: 59977.21627
If we subtract 6020 from 6800, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 14:
When dividing 7800 by 860, we get 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 59977.216279
The remainder is 60 after subtracting 7740 from 7800.
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 15:
The number 860 fits into 600 0 times, leaving a remainder of 600.
The next digit of our result is 0. 
Result so far: 59977.216279
If we subtract 0 from 600, we 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.

Moving on to step 16:
6000 divided by 860 is 6 with a remainder of 840.
Put 6 as the next digit of the answer. 
Result so far: 59977.21627906
If we subtract 5160 from 6000, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Our division results in 59977.21627906 with a remaining 8.4e-07.
