Let's divide 63971801 by 859
We want to divide 63971801 by 859.

Step 1:
6 divided by 859 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 859

Advancing to step 2:
859 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 859

Going ahead to step 3:
The number 859 fits into 639 0 times, leaving a remainder of 639.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 639 leaves us with 639.
Fetch the next digit (7) from the dividend, attach it to 639 and continue: 6397 / 859

Advancing to step 4:
859 can be fit into 6397 7 times, resulting in a remainder of 384.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 6013 from 6397 to get 384.
Take the next digit (1) from the dividend and append it to 384, then repeat: 3841 / 859

Going ahead to step 5:
The number 859 fits into 3841 4 times, leaving a remainder of 405.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we take 3436 away from 3841, we end up with 405.
Bring next digit (8) of the dividend behind the 405 and repeat the process: 4058 / 859

Let's proceed to step 6:
859 goes into 4058 4 times with a remainder of 622.
The number 4 becomes the next digit in our result. 
Result so far: 744.0
Subtracting 3436 from 4058 leaves us with 622.
Grab the next digit (0) from the dividend, add it to 622, then carry on: 6220 / 859

Moving on to step 7:
859 can be fit into 6220 7 times, resulting in a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 7447.0
The remainder is 207 after subtracting 6013 from 6220.
Append the next digit (1) from the dividend to 207 and continue with: 2071 / 859

Going ahead to step 8:
When dividing 2071 by 859, we get 2 with a remainder of 353.
Record the quotient 2 as the next digit in the result. 
Result so far: 74472.0
The remainder is 353 after subtracting 1718 from 2071.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 9:
3530 divided by 859 is 4 with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 74472.4
Deduct 3436 from 3530 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 10:
The number 859 fits into 940 1 times, leaving a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 74472.41
Deduct 859 from 940 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 11:
If we divide 810 by 859, we get 0 and a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 74472.41
If we take 0 away from 810, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 12:
859 can be fit into 8100 9 times, resulting in a remainder of 369.
Record the quotient 9 as the next digit in the result. 
Result so far: 74472.4109
Subtract 7731 from 8100 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 13:
3690 divided by 859 is 4 with a remainder of 254.
Use 4 as the next digit of our solution. 
Result so far: 74472.41094
Subtract 3436 from 3690 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 14:
2540 divided by 859 is 2 with a remainder of 822.
Record the quotient 2 as the next digit in the result. 
Result so far: 74472.410942
If we take 1718 away from 2540, we end up with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 15:
The number 859 fits into 8220 9 times, leaving a remainder of 489.
The number 9 becomes the next digit in our result. 
Result so far: 74472.4109429
The remainder is 489 after subtracting 7731 from 8220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 16:
When dividing 4890 by 859, we get 5 with a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 74472.41094295
The remainder is 595 after subtracting 4295 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

The final result is 74472.41094295 with a remainder of 5.95e-07.
