We look at the division of 39421283 by 649 
We want to figure out the number of times 39421283 can be divided by 649.

Going ahead to step 1:
The number 649 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 649

Let's proceed to step 2:
649 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 649

On to step 3:
649 goes into 394 0 times with a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 394 leaves us with 394.
Grab the next digit (2) from the dividend, add it to 394, then carry on: 3942 / 649

Let's proceed to step 4:
The number 649 fits into 3942 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 3894 from 3942 and we're left with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 649

Going ahead to step 5:
481 divided by 649 is 0 with a remainder of 481.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 481 and we're left with 481.
Include the next digit (2) from the dividend after 481, then repeat: 4812 / 649

Advancing to step 6:
If we divide 4812 by 649, we get 7 and a remainder of 269.
Write down 7 as next digit of the result. 
Result so far: 607.0
Subtract 4543 from 4812 to get 269.
Include the next digit (8) from the dividend after 269, then repeat: 2698 / 649

Going ahead to step 7:
The number 649 fits into 2698 4 times, leaving a remainder of 102.
The number 4 becomes the next digit in our result. 
Result so far: 6074.0
Deduct 2596 from 2698 and we're left with 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 649

On to step 8:
If we divide 1023 by 649, we get 1 and a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 60741.0
If we take 649 away from 1023, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 9:
If we divide 3740 by 649, we get 5 and a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 60741.5
The remainder is 495 after subtracting 3245 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 10:
649 goes into 4950 7 times with a remainder of 407.
The next digit of our result is 7. 
Result so far: 60741.57
Deduct 4543 from 4950 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 11:
If we divide 4070 by 649, we get 6 and a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 60741.576
If we subtract 3894 from 4070, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 12:
649 goes into 1760 2 times with a remainder of 462.
Put 2 as the next digit of the answer. 
Result so far: 60741.5762
Subtract 1298 from 1760 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 13:
649 goes into 4620 7 times with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 60741.57627
If we subtract 4543 from 4620, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
If we divide 770 by 649, we get 1 and a remainder of 121.
The next digit of our result is 1. 
Result so far: 60741.576271
If we take 649 away from 770, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 15:
When dividing 1210 by 649, we get 1 with a remainder of 561.
Use 1 as the next digit of our solution. 
Result so far: 60741.5762711
If we take 649 away from 1210, we end up with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

The final outcome is 60741.5762711, with a leftover of 5.61e-06.
