862421 ÷ 77 
We want to divide 862421 by 77.

Step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 77

Step 2:
86 divided by 77 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 86 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 77

On to step 3:
77 goes into 92 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 77 from 92 to get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 77

Step 4:
The number 77 fits into 154 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 154 from 154 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 77

Let's proceed to step 5:
77 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 1120.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 77

Going ahead to step 6:
The number 77 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 11200.0
Subtract 0 from 21 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
When dividing 210 by 77, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 11200.2
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
77 can be fit into 560 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 11200.27
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
77 goes into 210 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 11200.272
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
560 divided by 77 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 11200.2727
If we take 539 away from 560, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
When dividing 210 by 77, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 11200.27272
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
If we divide 560 by 77, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 11200.272727
Deduct 539 from 560 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
If we divide 210 by 77, we get 2 and a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 11200.2727272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
560 divided by 77 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 11200.27272727
Subtract 539 from 560 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 11200.27272727 and a remainder of 2.1e-08.
