We look at the division of 77683942 by 860 
We want to divide 77683942 by 860.

Going ahead to step 1:
860 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 860

Step 2:
If we divide 77 by 860, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 860

Moving on to step 3:
The number 860 fits into 776 0 times, leaving a remainder of 776.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 776, we end up with 776.
Append the next digit (8) from the dividend to 776 and continue with: 7768 / 860

On to step 4:
860 can be fit into 7768 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7740 away from 7768, we end up with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 860

Moving on to step 5:
If we divide 283 by 860, we get 0 and a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtract 0 from 283 to get 283.
Take the next digit (9) from the dividend and append it to 283, then repeat: 2839 / 860

Advancing to step 6:
The number 860 fits into 2839 3 times, leaving a remainder of 259.
The number 3 becomes the next digit in our result. 
Result so far: 903.0
Subtract 2580 from 2839 to get 259.
Fetch the next digit (4) from the dividend, attach it to 259 and continue: 2594 / 860

Let's proceed to step 7:
When dividing 2594 by 860, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 9033.0
If we subtract 2580 from 2594, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 860

Advancing to step 8:
142 divided by 860 is 0 with a remainder of 142.
Record the quotient 0 as the next digit in the result. 
Result so far: 90330.0
Subtracting 0 from 142 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
The number 860 fits into 1420 1 times, leaving a remainder of 560.
The next digit of our result is 1. 
Result so far: 90330.1
Subtract 860 from 1420 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 10:
860 can be fit into 5600 6 times, resulting in a remainder of 440.
Write down 6 as next digit of the result. 
Result so far: 90330.16
If we take 5160 away from 5600, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
860 can be fit into 4400 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 90330.165
If we take 4300 away from 4400, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
860 can be fit into 1000 1 times, resulting in a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 90330.1651
Deduct 860 from 1000 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
860 can be fit into 1400 1 times, resulting in a remainder of 540.
The number 1 becomes the next digit in our result. 
Result so far: 90330.16511
If we take 860 away from 1400, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Our division results in 90330.16511 with a remaining 0.00054.
