71738889 ÷ 561 
We want to figure out the number of times 71738889 can be divided by 561.

Advancing to step 1:
When dividing 7 by 561, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 561

Step 2:
561 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 561

Advancing to step 3:
If we divide 717 by 561, we get 1 and a remainder of 156.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 156 after subtracting 561 from 717.
Grab the next digit (3) from the dividend, add it to 156, then carry on: 1563 / 561

Let's proceed to step 4:
When dividing 1563 by 561, we get 2 with a remainder of 441.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 441 after subtracting 1122 from 1563.
Append the next digit (8) from the dividend to 441 and continue with: 4418 / 561

Step 5:
561 can be fit into 4418 7 times, resulting in a remainder of 491.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 3927 from 4418, we get 491.
Take the next digit (8) from the dividend and append it to 491, then repeat: 4918 / 561

Going ahead to step 6:
When dividing 4918 by 561, we get 8 with a remainder of 430.
The next digit of our result is 8. 
Result so far: 1278.0
If we take 4488 away from 4918, we end up with 430.
Grab the next digit (8) from the dividend, add it to 430, then carry on: 4308 / 561

Let's proceed to step 7:
4308 divided by 561 is 7 with a remainder of 381.
The number 7 becomes the next digit in our result. 
Result so far: 12787.0
The remainder is 381 after subtracting 3927 from 4308.
Bring next digit (9) of the dividend behind the 381 and repeat the process: 3819 / 561

Going ahead to step 8:
If we divide 3819 by 561, we get 6 and a remainder of 453.
Record the quotient 6 as the next digit in the result. 
Result so far: 127876.0
Subtract 3366 from 3819 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 9:
If we divide 4530 by 561, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 127876.8
The remainder is 42 after subtracting 4488 from 4530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
The number 561 fits into 420 0 times, leaving a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 127876.8
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
If we divide 4200 by 561, we get 7 and a remainder of 273.
The next digit of our result is 7. 
Result so far: 127876.807
The remainder is 273 after subtracting 3927 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 12:
2730 divided by 561 is 4 with a remainder of 486.
Put 4 as the next digit of the answer. 
Result so far: 127876.8074
Deduct 2244 from 2730 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 13:
561 can be fit into 4860 8 times, resulting in a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 127876.80748
If we take 4488 away from 4860, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 14:
When dividing 3720 by 561, we get 6 with a remainder of 354.
The next digit of our result is 6. 
Result so far: 127876.807486
If we take 3366 away from 3720, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 15:
When dividing 3540 by 561, we get 6 with a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 127876.8074866
Deduct 3366 from 3540 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Our division results in 127876.8074866 with a remaining 1.74e-06.
