40631530 ÷ 702 
We want to divide 40631530 by 702.

Going ahead to step 1:
The number 702 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 702

Step 2:
The number 702 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 702

Advancing to step 3:
The number 702 fits into 406 0 times, leaving a remainder of 406.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 406 after subtracting 0 from 406.
Include the next digit (3) from the dividend after 406, then repeat: 4063 / 702

On to step 4:
When dividing 4063 by 702, we get 5 with a remainder of 553.
The next digit of our result is 5. 
Result so far: 5.0
If we take 3510 away from 4063, we end up with 553.
Fetch the next digit (1) from the dividend, attach it to 553 and continue: 5531 / 702

Step 5:
702 goes into 5531 7 times with a remainder of 617.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 4914 from 5531 to get 617.
Grab the next digit (5) from the dividend, add it to 617, then carry on: 6175 / 702

Let's proceed to step 6:
702 can be fit into 6175 8 times, resulting in a remainder of 559.
The number 8 becomes the next digit in our result. 
Result so far: 578.0
If we take 5616 away from 6175, we end up with 559.
Append the next digit (3) from the dividend to 559 and continue with: 5593 / 702

Going ahead to step 7:
The number 702 fits into 5593 7 times, leaving a remainder of 679.
The number 7 becomes the next digit in our result. 
Result so far: 5787.0
Subtract 4914 from 5593 to get 679.
Bring next digit (0) of the dividend behind the 679 and repeat the process: 6790 / 702

Advancing to step 8:
702 can be fit into 6790 9 times, resulting in a remainder of 472.
Use 9 as the next digit of our solution. 
Result so far: 57879.0
The remainder is 472 after subtracting 6318 from 6790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 9:
If we divide 4720 by 702, we get 6 and a remainder of 508.
Put 6 as the next digit of the answer. 
Result so far: 57879.6
Deduct 4212 from 4720 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 10:
702 goes into 5080 7 times with a remainder of 166.
Put 7 as the next digit of the answer. 
Result so far: 57879.67
The remainder is 166 after subtracting 4914 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 11:
702 can be fit into 1660 2 times, resulting in a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 57879.672
If we subtract 1404 from 1660, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 12:
If we divide 2560 by 702, we get 3 and a remainder of 454.
The number 3 becomes the next digit in our result. 
Result so far: 57879.6723
If we subtract 2106 from 2560, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 13:
The number 702 fits into 4540 6 times, leaving a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 57879.67236
The remainder is 328 after subtracting 4212 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 14:
The number 702 fits into 3280 4 times, leaving a remainder of 472.
The next digit of our result is 4. 
Result so far: 57879.672364
Subtract 2808 from 3280 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 15:
4720 divided by 702 is 6 with a remainder of 508.
The number 6 becomes the next digit in our result. 
Result so far: 57879.6723646
If we subtract 4212 from 4720, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 16:
When dividing 5080 by 702, we get 7 with a remainder of 166.
The next digit of our result is 7. 
Result so far: 57879.67236467
The remainder is 166 after subtracting 4914 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final outcome is 57879.67236467, with a leftover of 1.66e-07.
