We divide 63985259 by 840
Our goal is to divide 63985259 by 840.

Let's proceed to step 1:
When dividing 6 by 840, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 840

On to step 2:
If we divide 63 by 840, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 840

Step 3:
639 divided by 840 is 0 with a remainder of 639.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 639, we end up with 639.
Include the next digit (8) from the dividend after 639, then repeat: 6398 / 840

On to step 4:
840 can be fit into 6398 7 times, resulting in a remainder of 518.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5880 from 6398 to get 518.
Take the next digit (5) from the dividend and append it to 518, then repeat: 5185 / 840

On to step 5:
When dividing 5185 by 840, we get 6 with a remainder of 145.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 145 after subtracting 5040 from 5185.
Fetch the next digit (2) from the dividend, attach it to 145 and continue: 1452 / 840

On to step 6:
The number 840 fits into 1452 1 times, leaving a remainder of 612.
Put 1 as the next digit of the answer. 
Result so far: 761.0
Subtracting 840 from 1452 leaves us with 612.
Fetch the next digit (5) from the dividend, attach it to 612 and continue: 6125 / 840

Let's proceed to step 7:
If we divide 6125 by 840, we get 7 and a remainder of 245.
The number 7 becomes the next digit in our result. 
Result so far: 7617.0
Deduct 5880 from 6125 and we're left with 245.
Include the next digit (9) from the dividend after 245, then repeat: 2459 / 840

On to step 8:
840 can be fit into 2459 2 times, resulting in a remainder of 779.
The number 2 becomes the next digit in our result. 
Result so far: 76172.0
Deduct 1680 from 2459 and we're left with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Going ahead to step 9:
840 goes into 7790 9 times with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 76172.9
If we subtract 7560 from 7790, we get 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:
The number 840 fits into 2300 2 times, leaving a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 76172.92
Deduct 1680 from 2300 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 11:
6200 divided by 840 is 7 with a remainder of 320.
The next digit of our result is 7. 
Result so far: 76172.927
Deduct 5880 from 6200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
When dividing 3200 by 840, we get 3 with a remainder of 680.
Put 3 as the next digit of the answer. 
Result so far: 76172.9273
Deduct 2520 from 3200 and we're left 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.

Going ahead to step 13:
6800 divided by 840 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 76172.92738
If we subtract 6720 from 6800, we get 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.
Put 0 as the next digit of the answer. 
Result so far: 76172.92738
If we take 0 away from 800, we end up with 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:
840 can be fit into 8000 9 times, resulting in a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 76172.9273809
Subtract 7560 from 8000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 16:
The number 840 fits into 4400 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 76172.92738095
Subtracting 4200 from 4400 leaves us with 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 76172.92738095, with a leftover of 2e-07.
