66968891 divided by 189 
We want to divide 66968891 by 189.

On to step 1:
6 divided by 189 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 189

Let's proceed to step 2:
66 divided by 189 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 189

Advancing to step 3:
189 can be fit into 669 3 times, resulting in a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 102 after subtracting 567 from 669.
Grab the next digit (6) from the dividend, add it to 102, then carry on: 1026 / 189

Advancing to step 4:
If we divide 1026 by 189, we get 5 and a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 945 from 1026 and we're left with 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 189

Advancing to step 5:
If we divide 818 by 189, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 354.0
Deduct 756 from 818 and we're left with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 189

Let's proceed to step 6:
189 can be fit into 628 3 times, resulting in a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 3543.0
If we subtract 567 from 628, we get 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 189

On to step 7:
189 goes into 619 3 times with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 35433.0
If we take 567 away from 619, we end up with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 189

Let's proceed to step 8:
The number 189 fits into 521 2 times, leaving a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 354332.0
The remainder is 143 after subtracting 378 from 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 9:
189 can be fit into 1430 7 times, resulting in a remainder of 107.
The next digit of our result is 7. 
Result so far: 354332.7
If we subtract 1323 from 1430, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 10:
When dividing 1070 by 189, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 354332.75
Deduct 945 from 1070 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
189 can be fit into 1250 6 times, resulting in a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 354332.756
Subtracting 1134 from 1250 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 12:
If we divide 1160 by 189, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 354332.7566
The remainder is 26 after subtracting 1134 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 354332.7566 with a balance of 0.00026.
