Moving on to step 5:
7535 divided by 840 is 8 with a remainder of 815.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 6720 from 7535 leaves us with 815.
Fetch the next digit (7) from the dividend, attach it to 815 and continue: 8157 / 840

Step 6:
8157 divided by 840 is 9 with a remainder of 597.
Write down 9 as next digit of the result. 
Result so far: 889.0
The remainder is 597 after subtracting 7560 from 8157.
Append the next digit (8) from the dividend to 597 and continue with: 5978 / 840

Moving on to step 7:
840 can be fit into 5978 7 times, resulting in a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 8897.0
If we take 5880 away from 5978, we end up with 98.
Take the next digit (8) from the dividend and append it to 98, then repeat: 988 / 840

Let's proceed to step 8:
840 can be fit into 988 1 times, resulting in a remainder of 148.
The next digit of our result is 1. 
Result so far: 88971.0
Subtract 840 from 988 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 9:
840 can be fit into 1480 1 times, resulting in a remainder of 640.
The next digit of our result is 1. 
Result so far: 88971.1
Subtract 840 from 1480 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
If we divide 6400 by 840, we get 7 and a remainder of 520.
Record the quotient 7 as the next digit in the result. 
Result so far: 88971.17
Deduct 5880 from 6400 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
When dividing 5200 by 840, we get 6 with a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 88971.176
Deduct 5040 from 5200 and we're left 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 12:
1600 divided by 840 is 1 with a remainder of 760.
Record the quotient 1 as the next digit in the result. 
Result so far: 88971.1761
Subtract 840 from 1600 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 13:
7600 divided by 840 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 88971.17619
If we take 7560 away from 7600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
840 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 88971.17619
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 15:
The number 840 fits into 4000 4 times, leaving a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 88971.1761904
Subtracting 3360 from 4000 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 16:
If we divide 6400 by 840, we get 7 and a remainder of 520.
Record the quotient 7 as the next digit in the result. 
Result so far: 88971.17619047
Subtracting 5880 from 6400 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 88971.17619047 with a remaining 5.2e-07.
