73649961 ÷ 159 
Our goal is to divide 73649961 by 159.

Going ahead to step 1:
159 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 159

Going ahead to step 2:
73 divided by 159 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 159

Moving on to step 3:
If we divide 736 by 159, we get 4 and a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 636 from 736, we get 100.
Append the next digit (4) from the dividend to 100 and continue with: 1004 / 159

Advancing to step 4:
When dividing 1004 by 159, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 50 after subtracting 954 from 1004.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 159

Step 5:
509 divided by 159 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 463.0
Deduct 477 from 509 and we're left with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 159

Going ahead to step 6:
If we divide 329 by 159, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 4632.0
Subtract 318 from 329 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 159

Advancing to step 7:
When dividing 116 by 159, we get 0 with a remainder of 116.
The next digit of our result is 0. 
Result so far: 46320.0
Subtract 0 from 116 to get 116.
Fetch the next digit (1) from the dividend, attach it to 116 and continue: 1161 / 159

Step 8:
The number 159 fits into 1161 7 times, leaving a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 463207.0
Deduct 1113 from 1161 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
159 goes into 480 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 463207.3
Subtracting 477 from 480 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
The number 159 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 463207.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 159, we get 1 with a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 463207.301
Subtracting 159 from 300 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 12:
1410 divided by 159 is 8 with a remainder of 138.
The next digit of our result is 8. 
Result so far: 463207.3018
If we subtract 1272 from 1410, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 13:
1380 divided by 159 is 8 with a remainder of 108.
The next digit of our result is 8. 
Result so far: 463207.30188
Deduct 1272 from 1380 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 463207.30188 with a remainder of 0.000108.
