86996380 ÷ 840 
We want to divide 86996380 by 840.

Going ahead to step 1:
840 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 840

Let's proceed to step 2:
The number 840 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 840

Let's proceed to step 3:
840 goes into 869 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 840 from 869, we get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 840

Moving on to step 4:
840 can be fit into 299 0 times, resulting in a remainder of 299.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 299 leaves us with 299.
Grab the next digit (6) from the dividend, add it to 299, then carry on: 2996 / 840

Moving on to step 5:
When dividing 2996 by 840, we get 3 with a remainder of 476.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 2520 from 2996 and we're left with 476.
Bring next digit (3) of the dividend behind the 476 and repeat the process: 4763 / 840

Advancing to step 6:
840 goes into 4763 5 times with a remainder of 563.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
The remainder is 563 after subtracting 4200 from 4763.
Take the next digit (8) from the dividend and append it to 563, then repeat: 5638 / 840

Moving on to step 7:
840 can be fit into 5638 6 times, resulting in a remainder of 598.
Put 6 as the next digit of the answer. 
Result so far: 10356.0
Deduct 5040 from 5638 and we're left with 598.
Grab the next digit (0) from the dividend, add it to 598, then carry on: 5980 / 840

Moving on to step 8:
5980 divided by 840 is 7 with a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 103567.0
Deduct 5880 from 5980 and we're left 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 9:
When dividing 1000 by 840, we get 1 with a remainder of 160.
The number 1 becomes the next digit in our result. 
Result so far: 103567.1
If we take 840 away from 1000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
If we divide 1600 by 840, we get 1 and a remainder of 760.
Use 1 as the next digit of our solution. 
Result so far: 103567.11
The remainder is 760 after subtracting 840 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The quotient of the division is 103567.11, and the remainder is 0.76.
