We're dividing 63998967 by 412 
Our goal is to divide 63998967 by 412.

Advancing to step 1:
When dividing 6 by 412, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 412

Advancing to step 2:
63 divided by 412 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 412

Advancing to step 3:
412 can be fit into 639 1 times, resulting in a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 412 from 639 to get 227.
Grab the next digit (9) from the dividend, add it to 227, then carry on: 2279 / 412

Moving on to step 4:
412 goes into 2279 5 times with a remainder of 219.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2060 from 2279 and we're left with 219.
Include the next digit (8) from the dividend after 219, then repeat: 2198 / 412

Let's proceed to step 5:
The number 412 fits into 2198 5 times, leaving a remainder of 138.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Deduct 2060 from 2198 and we're left with 138.
Include the next digit (9) from the dividend after 138, then repeat: 1389 / 412

Advancing to step 6:
412 can be fit into 1389 3 times, resulting in a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 1553.0
If we subtract 1236 from 1389, we get 153.
Include the next digit (6) from the dividend after 153, then repeat: 1536 / 412

Moving on to step 7:
When dividing 1536 by 412, we get 3 with a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 15533.0
If we take 1236 away from 1536, we end up with 300.
Append the next digit (7) from the dividend to 300 and continue with: 3007 / 412

Going ahead to step 8:
412 goes into 3007 7 times with a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 155337.0
If we subtract 2884 from 3007, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
The number 412 fits into 1230 2 times, leaving a remainder of 406.
Use 2 as the next digit of our solution. 
Result so far: 155337.2
Subtracting 824 from 1230 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 10:
When dividing 4060 by 412, we get 9 with a remainder of 352.
Write down 9 as next digit of the result. 
Result so far: 155337.29
Subtract 3708 from 4060 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 11:
If we divide 3520 by 412, we get 8 and a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 155337.298
If we take 3296 away from 3520, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 12:
When dividing 2240 by 412, we get 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 155337.2985
If we take 2060 away from 2240, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
When dividing 1800 by 412, we get 4 with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 155337.29854
Subtract 1648 from 1800 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 14:
412 goes into 1520 3 times with a remainder of 284.
Record the quotient 3 as the next digit in the result. 
Result so far: 155337.298543
If we take 1236 away from 1520, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 15:
412 can be fit into 2840 6 times, resulting in a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 155337.2985436
If we take 2472 away from 2840, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 16:
If we divide 3680 by 412, we get 8 and a remainder of 384.
The next digit of our result is 8. 
Result so far: 155337.29854368
If we subtract 3296 from 3680, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 155337.29854368 with a remainder of 3.84e-07.
