We look at the division of 90970497 by 673 
We want to divide 90970497 by 673.

On to step 1:
If we divide 9 by 673, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 673

Step 2:
90 divided by 673 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 673

Moving on to step 3:
909 divided by 673 is 1 with a remainder of 236.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 673 from 909, we get 236.
Include the next digit (7) from the dividend after 236, then repeat: 2367 / 673

Let's proceed to step 4:
The number 673 fits into 2367 3 times, leaving a remainder of 348.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 2019 away from 2367, we end up with 348.
Grab the next digit (0) from the dividend, add it to 348, then carry on: 3480 / 673

Going ahead to step 5:
When dividing 3480 by 673, we get 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 3365 from 3480 and we're left with 115.
Bring next digit (4) of the dividend behind the 115 and repeat the process: 1154 / 673

Advancing to step 6:
1154 divided by 673 is 1 with a remainder of 481.
The number 1 becomes the next digit in our result. 
Result so far: 1351.0
Subtracting 673 from 1154 leaves us with 481.
Bring next digit (9) of the dividend behind the 481 and repeat the process: 4819 / 673

Let's proceed to step 7:
4819 divided by 673 is 7 with a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 13517.0
The remainder is 108 after subtracting 4711 from 4819.
Append the next digit (7) from the dividend to 108 and continue with: 1087 / 673

Let's proceed to step 8:
When dividing 1087 by 673, we get 1 with a remainder of 414.
Write down 1 as next digit of the result. 
Result so far: 135171.0
If we take 673 away from 1087, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 9:
If we divide 4140 by 673, we get 6 and a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 135171.6
If we take 4038 away from 4140, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
If we divide 1020 by 673, we get 1 and a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 135171.61
If we take 673 away from 1020, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 11:
3470 divided by 673 is 5 with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 135171.615
The remainder is 105 after subtracting 3365 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 12:
673 can be fit into 1050 1 times, resulting in a remainder of 377.
Put 1 as the next digit of the answer. 
Result so far: 135171.6151
Subtract 673 from 1050 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 13:
673 can be fit into 3770 5 times, resulting in a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 135171.61515
Deduct 3365 from 3770 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 14:
673 goes into 4050 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 135171.615156
If we take 4038 away from 4050, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 15:
673 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 135171.615156
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
1200 divided by 673 is 1 with a remainder of 527.
The next digit of our result is 1. 
Result so far: 135171.61515601
Deduct 673 from 1200 and we're left with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Our division results in 135171.61515601 with a remaining 5.27e-07.
