91473789 ÷ 123 
Our goal is to divide 91473789 by 123.

Let's proceed to step 1:
The number 123 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 123

Going ahead to step 2:
91 divided by 123 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 123

Step 3:
If we divide 914 by 123, we get 7 and a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 861 from 914, we get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 123

Advancing to step 4:
123 goes into 537 4 times with a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 492 from 537, we get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 123

Advancing to step 5:
The number 123 fits into 453 3 times, leaving a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 743.0
The remainder is 84 after subtracting 369 from 453.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 123

Step 6:
The number 123 fits into 847 6 times, leaving a remainder of 109.
Write down 6 as next digit of the result. 
Result so far: 7436.0
If we take 738 away from 847, we end up with 109.
Append the next digit (8) from the dividend to 109 and continue with: 1098 / 123

On to step 7:
123 can be fit into 1098 8 times, resulting in a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 74368.0
Subtracting 984 from 1098 leaves us with 114.
Append the next digit (9) from the dividend to 114 and continue with: 1149 / 123

Step 8:
123 can be fit into 1149 9 times, resulting in a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 743689.0
If we take 1107 away from 1149, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
123 goes into 420 3 times with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 743689.3
Deduct 369 from 420 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
123 can be fit into 510 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 743689.34
The remainder is 18 after subtracting 492 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
123 can be fit into 180 1 times, resulting in a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 743689.341
Subtract 123 from 180 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
If we divide 570 by 123, we get 4 and a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 743689.3414
The remainder is 78 after subtracting 492 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
123 can be fit into 780 6 times, resulting in a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 743689.34146
Subtract 738 from 780 to get 42.
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 14:
123 can be fit into 420 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 743689.341463
Deduct 369 from 420 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 15:
When dividing 510 by 123, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 743689.3414634
The remainder is 18 after subtracting 492 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 16:
123 can be fit into 180 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 743689.34146341
If we take 123 away from 180, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

In conclusion, the division gives 743689.34146341 with a balance of 5.7e-08.
