60142343 ÷ 840 
Our goal is to divide 60142343 by 840.

Going ahead to step 1:
When dividing 6 by 840, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 840

Let's proceed to step 2:
60 divided by 840 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 840

Advancing to step 3:
The number 840 fits into 601 0 times, leaving a remainder of 601.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 601 to get 601.
Include the next digit (4) from the dividend after 601, then repeat: 6014 / 840

Advancing to step 4:
840 goes into 6014 7 times with a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 134 after subtracting 5880 from 6014.
Fetch the next digit (2) from the dividend, attach it to 134 and continue: 1342 / 840

Advancing to step 5:
When dividing 1342 by 840, we get 1 with a remainder of 502.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtract 840 from 1342 to get 502.
Bring next digit (3) of the dividend behind the 502 and repeat the process: 5023 / 840

Let's proceed to step 6:
If we divide 5023 by 840, we get 5 and a remainder of 823.
Record the quotient 5 as the next digit in the result. 
Result so far: 715.0
Deduct 4200 from 5023 and we're left with 823.
Fetch the next digit (4) from the dividend, attach it to 823 and continue: 8234 / 840

Advancing to step 7:
840 can be fit into 8234 9 times, resulting in a remainder of 674.
Put 9 as the next digit of the answer. 
Result so far: 7159.0
The remainder is 674 after subtracting 7560 from 8234.
Take the next digit (3) from the dividend and append it to 674, then repeat: 6743 / 840

Going ahead to step 8:
When dividing 6743 by 840, we get 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 71598.0
Subtract 6720 from 6743 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
If we divide 230 by 840, we get 0 and a remainder of 230.
The next digit of our result is 0. 
Result so far: 71598.0
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
2300 divided by 840 is 2 with a remainder of 620.
Use 2 as the next digit of our solution. 
Result so far: 71598.02
The remainder is 620 after subtracting 1680 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 11:
840 can be fit into 6200 7 times, resulting in a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 71598.027
The remainder is 320 after subtracting 5880 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
If we divide 3200 by 840, we get 3 and a remainder of 680.
Write down 3 as next digit of the result. 
Result so far: 71598.0273
Subtracting 2520 from 3200 leaves us with 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:
840 goes into 6800 8 times with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 71598.02738
Deduct 6720 from 6800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
The number 840 fits into 800 0 times, leaving a remainder of 800.
The next digit of our result is 0. 
Result so far: 71598.02738
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 15:
The number 840 fits into 8000 9 times, leaving a remainder of 440.
Put 9 as the next digit of the answer. 
Result so far: 71598.0273809
The remainder is 440 after subtracting 7560 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 16:
When dividing 4400 by 840, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 71598.02738095
If we subtract 4200 from 4400, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 71598.02738095, with a leftover of 2e-07.
