63449359 ÷ 946 
We want to divide 63449359 by 946.

Moving on to step 1:
If we divide 6 by 946, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 946

On to step 2:
946 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 946

Advancing to step 3:
When dividing 634 by 946, we get 0 with a remainder of 634.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 634 to get 634.
Include the next digit (4) from the dividend after 634, then repeat: 6344 / 946

Moving on to step 4:
The number 946 fits into 6344 6 times, leaving a remainder of 668.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5676 from 6344 leaves us with 668.
Take the next digit (9) from the dividend and append it to 668, then repeat: 6689 / 946

Step 5:
If we divide 6689 by 946, we get 7 and a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 6622 from 6689 and we're left with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 946

Going ahead to step 6:
The number 946 fits into 673 0 times, leaving a remainder of 673.
Put 0 as the next digit of the answer. 
Result so far: 670.0
Subtract 0 from 673 to get 673.
Take the next digit (5) from the dividend and append it to 673, then repeat: 6735 / 946

Going ahead to step 7:
If we divide 6735 by 946, we get 7 and a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 6707.0
Subtracting 6622 from 6735 leaves us with 113.
Fetch the next digit (9) from the dividend, attach it to 113 and continue: 1139 / 946

Let's proceed to step 8:
If we divide 1139 by 946, we get 1 and a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 67071.0
The remainder is 193 after subtracting 946 from 1139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 9:
1930 divided by 946 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 67071.2
Subtract 1892 from 1930 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
946 can be fit into 380 0 times, resulting in a remainder of 380.
The next digit of our result is 0. 
Result so far: 67071.2
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
If we divide 3800 by 946, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 67071.204
If we subtract 3784 from 3800, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 946, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 67071.204
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
If we divide 1600 by 946, we get 1 and a remainder of 654.
Use 1 as the next digit of our solution. 
Result so far: 67071.20401
If we take 946 away from 1600, we end up with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 14:
946 goes into 6540 6 times with a remainder of 864.
The number 6 becomes the next digit in our result. 
Result so far: 67071.204016
Subtracting 5676 from 6540 leaves us with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Moving on to step 15:
946 can be fit into 8640 9 times, resulting in a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 67071.2040169
If we take 8514 away from 8640, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 16:
946 goes into 1260 1 times with a remainder of 314.
The next digit of our result is 1. 
Result so far: 67071.20401691
Subtract 946 from 1260 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final result is 67071.20401691 with a remainder of 3.14e-07.
